Delay in booting 2.6.14 on SATA laptop

This is my first post to the board so I like to say hello to the community.

I face a problem when booting my laptop with the kernel 2.6.14. During bootup the process gets to a rest for about 90 seconds. After that time, the boot process finishes successfully.

The laptop is a FujitsuSiemens Lifbebook s7020 with the follwing hardware:
Centrino "Sonoma" P760 (2 Ghz)
Intel i915 PCI Express
SXGA+ at 14" (1400x1050)
DD 80Go SATA
Ethernet Broadcom 1 Gb/s tigon 3
Intel Pro Wireless 2200 BG
Bluetooth / FireWire ieee 1394

Many thanks for your help.

Re: Delay in booting 2.6.14 on SATA laptop

if you run kernel from testing with initrd modify your /etc/mkinitrd.conf to not use scsi and rebuild it, then the scsi modules are not included anymore and boot should be faster.

Re: Delay in booting 2.6.14 on SATA laptop

If I switch off SCSI, the kernel will not boot at all. I learned, that SATA drives are seen as SCSI drives (and therefore, the SCSI should not switched off) , but I might be wrong with that...(?)

Hmm, then keep scsi on - try to configure /etc/mkinitrd.conf for your specific hardware.  You can use hwdetect to dump the modules for your hardware, and then add them to the config - details should be in the wiki.

With a custom initrd, see if the boot speed changes.  If it does, that we can track down what causes the hang in the full image.

hwdetect says:

so changed mkinitrd.conf to:

REMOVE_FW=1
REMOVE_RAID=1

HOSTCONTROLLER_IDE="ide-cd ide-core generic piix"

HOSTCONTROLLER_SATA="ata_piix libata"
HOSTCONTROLLER_USB="usb-storage usblp usbhid usbcore ehci-hcd uhci-hcd"
FILESYSTEMS="ext3 reiserfs"

but system still waits at the point shown above for about 90 seconds like as it waits for a timeout to happen in ahci...?

turn off the autodetection and see if that's the culprit

Re: Delay in booting 2.6.14 on SATA laptop

Switched off autodetection and made mkinitrd auto but no success.

In kernel.log I found this message:

This sequence looks similar than the one in my first post, which was copied out of messages.log. In addition there is the message 'PCI: Setting latency timer of device 0000:00:1f.2 to 64' ( >> inserted to emphasize).
I then more careful timed the delay with a stopwatch and found out, that the delay is around these 64 seconds mentioned in the message.
The message itself appears on other places before the sequenze shown above:

Dec 15 09:50:40 (none) PCI: Setting latency timer of device 0000:00:1c.0 to 64
Dec 15 09:50:40 (none) PCI: Device 0000:00:1c.1 not available because of resource collisions
Dec 15 09:50:40 (none) PCI: Setting latency timer of device 0000:00:1c.1 to 64
Dec 15 09:50:40 (none) PCI: Setting latency timer of device 0000:00:1e.0 to 64

the process however stops only once for these 64 seconds. Can this latency timer be the cause of the delay? If yes, can it be influenced (set lower) somewhere?

I need to point out something here, and this may fix your problem.  In the initrd you only need the modules to mount your root device.  That would be whatever you have in the "root=/dev/blah" line in menu.lst/lilo.conf - you need nothing else.

Remove everything else, and try again - I have a feeling the 90s delay may be from usb stuff, which you don't need.

Re: Delay in booting 2.6.14 on SATA laptop

Thank you, phrakture for the advice. As soon as I had set REMOVE_IDE= 1, the problem was gone. I then also tried to switch off SCSI and this time I was able to boot. Maybe something in the kernel has changed. I am one of the early adopter of ARCH 0.7.1 (right when the version was put on the net, I owned a new laptop so I thought, I would take the challenge and set it up with 0.7.1) I am sure, that the laptop then failed to boot when either IDE or SCSI was set to 1 so I was afraid to switch it off again...

My mkinitrd.conf now looks like:

REMOVE_IDE=1
REMOVE_SCSI=1
REMOVE_SATA=
REMOVE_CDROM=1
REMOVE_USB=1
REMOVE_FW=1
REMOVE_RAID=1
REMOVE_DM=1
REMOVE_FS=

AUTODETECT=1

HOSTCONTROLLER_IDE=
HOSTCONTROLLER_SCSI=
HOSTCONTROLLER_SATA="ata_piix libata"
HOSTCONTROLLER_USB=
FILESYSTEMS="ext3 reiserfs"

Many thanks for all the help and have a nice day

Re: Delay in booting 2.6.14 on SATA laptop

I'm pretty sure you don't need libata in HOSTCONTROLLER_SATA. It'll be loaded automatically. At least that's how it works on my i915 based notebook. Also hwdetect has special options for scanning modules to be used in mkinitrd. Check your lsmod output for more modules to be eliminated.

Re: Delay in booting 2.6.14 on SATA laptop

Hmm, it looks like it's a problem with the ide modules themselves... like the *almost* detect your drive, then decide to give up.

PS You don't need 2 file systems in the initrd unless you have two possible "/" root partitions - you only need the filesystem for the partition listed on the "root=/dev/*" kernel parameter.

edit PPS Can you please bug report this - it might be something we can take care of somehow (I promise nothing, heh).  Please provide all information for your system - that is 'lspci' info, 'hwdetect --show-modules' and anything else related to the hardware you can think of.  Thanks.

Re: Delay in booting 2.6.14 on SATA laptop

As smurf, i tried to remove every module in /etc/mkinitrd.conf but SATA module for my boxes.

But as soon as I add "1" in 'REMOVE_CDROM=' I find neither cd* neither dvd in /dev
Therefore I can't mount or use the CD/DVD optical drives.

That's on a 100% IDE Dell PIII as well on my asrock Dual sata2 boxes with IDE NEC drive.
How comes i have to add CDrom module in /etc/mkinitrd.conf so the system can see the optical drives ?

you don't have to put them in initrd, you can simply load ide-cd or whatever modules you need in rc.conf. the reason you didn't have to do this before is that the cd modules aren't built into the kernel anymore, they need to be loaded.

remember, initrd only needs to include the modules required to mount root. everything else belongs in rc.conf

That's the clearest string (your 2 phrases put together) I've read on this subject smile

I'm presently in the middle of downloading a very big torrent file I'd like not to interrupt (File hashing takes forever on x GB) but I edited both files so that they look like this :

# /etc/rc.conf - Main Configuration for Arch Linux
#
# hwdetect :
MOD_AUTOLOAD="yes"
MOD_BLACKLIST=()
# initrd only needs to include the modules required to mount root.
# everything else belongs in rc.conf :
MODULES=(!usbserial !ide-scsi sata_uli ide_cd uli526x)

&

# /etc/mkinitrd.conf - load those modules that are necessary to boot the "/" partition
#
REMOVE_IDE=1
REMOVE_SCSI=1
REMOVE_SATA=
REMOVE_CDROM=1
REMOVE_USB=1
REMOVE_FW=1
REMOVE_RAID=1
REMOVE_DM=1

#

#
# Define which modules are needed by adding "moduleX moduleY"
# If left empty, all modules are included if they are not disabled above

HOSTCONTROLLER_SCSI=
HOSTCONTROLLER_SATA=sata_uli

Hope it will do the job nicelly

Re: Delay in booting 2.6.14 on SATA laptop

There are  some mainstream problems using dvd/cdrw with sata/ide drivers at the same time.
A good explanation is available at these webpages:
1. thinkwiki
2. redhat bugzilla
3. kerneltrap

Basically my notebook dvd/cdrw should work with sata drivers. And it's being recognized by the kernel. But the standard drivers do not have PATA ATAPI support enabled by default and there is no device link under /dev so you can't mount it. And if the ide driver is loaded after sata driver it will not be able to take ownership of dvd device producing a long delay on kernel boot (kernel will boot fine though).

There are a few workarounds described on the above webpages. You can try to force ide_generic driver for dvd/cdrw using HOSTCONTROLLER_IDE="ide_generic piix" and HOSTCONTROLLER_SATA="ata_piix" in /etc/mkinird.conf. This will load the ide_generic driver first but your /dev/sda will become /dev/hda and boot will fail. It should be fixable by adding some options to /etc/modprobe.conf and regenerating initrd (details in the links) but even if it works you'll not be able to use DMA for dvd/cdrw. I didn't go that far (no time) so this is only a theory. You can also enable the experimental PATA ATAPI option for sata driver and have a /dev link + DMA enabled but it's... well experimental :-)

Meanwhile there is a new kernel in the upgrade que. We'll see how it works without any modifications.

This in fact happened with me as well, when I had the delay in booting, but I did not check it right now. I do not need the CDROM very often and so I did not pay attention if the driver was loaded or not. I will check that in a few hours.

phrakture wrote: PS You don't need 2 file systems in the initrd unless you have two possible "/" root partitions - you only need the filesystem for the partition listed on the "root=/dev/*" kernel parameter.

You are right. I was not consequent enough with removing everything, which is not needed to mount the root device. I will do that.

edit PPS Can you please bug report this - it might be something we can take care of somehow

'Bug report' sounds to me rather malignant... but if it helps to further improve Arch, I will try to file my first bug report...

Re: Delay in booting 2.6.14 on SATA laptop

The CDROM disappeared after my changes in mkinitrd.conf. After enabeling IDE (removed the "1" from REMOVE_IDE=), the CD was here again and could be mounted. I did not check however, if DMA can be influenced. Looks like initrd loads the correct driver for the CD although it is not used for booting. To my embarassement, the delay in booting was gone, although it seemed, that the IDE part was the reason for the delay. What finally is different in mkinitrd.conf to my first post is:

REMOVE_IDE=
REMOVE_SCSI=1 (switched off)
REMOVE_SATA=
REMOVE_CDROM=1 (switched off)
REMOVE_USB=1
REMOVE_FW=1
REMOVE_RAID=1
REMOVE_DM=1
REMOVE_FS=

AUTODETECT=0  (set from 1 to 0)

HOSTCONTROLLER_IDE=
HOSTCONTROLLER_SCSI=
HOSTCONTROLLER_SATA="ata_piix" (added ata_piix)
HOSTCONTROLLER_USB=
FILESYSTEMS="reiserfs" (removed ext3 where /boot is)

I am happy with that setup for the FujitsuSiemens s7020. The CD is usable but maybe not tweakable (did not check yet) so lanrats' advice or kozakis' setup might be better for certain laptops or systems.
