[solved] kernel 3.6 does not recognize my pata DVD and CDROM

With kernel 3.6.2 from testing my CDROM and DVD drive are not recognized anymore. This used to work flawlessly until 3.5.6.

This is how it used to be in kernel 3.5.6

If I read this correctly it is a problem with ACPI. The ACPID daemon is not running in my system.

Any hints?

Re: [solved] kernel 3.6 does not recognize my pata DVD and CDROM

You could add "libata.noacpi=1" to your kernel command line and see if that helps.

Re: [solved] kernel 3.6 does not recognize my pata DVD and CDROM

So here is what I think after some research:

according to lspci I have an SATA controller: JMicron Technology Corp. JMB363 SATA/IDE Controller (rev 02) (prog-if 01 [AHCI 1.0])
It has a pata part too where my two pata cdrom/dvd drives are attached.

In kernel 3.6 a change in this area has been made:
http://kernelnewbies.org/Linux_3.6_DriverArch
http://git.kernel.org/linus/1fefb8fdc65 … 23981c9686

Could this be a kernel bug?

Re: [solved] kernel 3.6 does not recognize my pata DVD and CDROM

I can confirm this bug on my hardware, sincgle chip with two controllers for me too:

03:00.0 SATA controller: JMicron Technology Corp. JMB361 AHCI/IDE (rev 02)
03:00.1 IDE interface: JMicron Technology Corp. JMB361 AHCI/IDE (rev 02)

The problem is that 3.6.2 landed to core repo, and for me this is a critical bug, cause my system fails booting and prompt me for maintanance mode.
Two strange things:
1) My system fails to boot with new kernel despite my system partitions are all on a Sata disk.
2) System keeps falling even if I disable Ide controller from Bios.

With Ide enabled I see some error lines about ide timing, then after finding my /home partition (that's on sata disk) it hang for almost a minute then prmpt to me for maintance mode. Ok, I thought, it cannot find the Pata disk where my archive partition disk resides, and it hangs (a little bit weird but acceptable).
I disable Ide from Bios, no error lines get shown... but it hangs in the same way.

Now I re-installed 3.5 from maintanance, and unfortunately I had no persistant journald log set when I tred to run new kernel, so I cannot be more precise on troubleshooting. If you need better information, I can re-install, try to reboot, back to 3.5 etc. etc. and post you my log.

I agree that this is a pretty bad bug for you. sad

I fear there will be no way out of this until the kernel will be corrected. My only luck ist that my jmicron is only an alongside to another sata controller on which my sata disks are, so only my ATA drives connected to this controller are gone for now.  I contacted the kernel developer responsible for the commit. Let's see if there is a response. If not, we will have to report this to the kernel bugtracker.

Re: [solved] kernel 3.6 does not recognize my pata DVD and CDROM

I re-checked again my configuration. Actually Jmicron sata controller, just manages one e-sata slot (that I don't use neither). My disk too is on one of this two integrated controller

00:1f.2 IDE interface: Intel Corporation 82801JI (ICH10 Family) 4 port SATA IDE Controller #1
00:1f.5 IDE interface: Intel Corporation 82801JI (ICH10 Family) 2 port SATA IDE Controller #2

Now I really can't understand why this bug is blocker for me. hmm

Re: [solved] kernel 3.6 does not recognize my pata DVD and CDROM

I have the same problem with 4javier.

Boot stops on udev, searching for a PATA disk which i have only for data.Then it falls to maintanance mode because it can't find the root partition (which is on a SATA disk).

00:14.1 IDE interface: Advanced Micro Devices [AMD] nee ATI IXP SB400 IDE Controller
00:12.0 IDE interface: Advanced Micro Devices [AMD] nee ATI IXP SB400 Serial ATA Controller

Re: [solved] kernel 3.6 does not recognize my pata DVD and CDROM

It seems that the bug strikes on different types of ATA/SATA interface drivers.
Here the link to the bugzilla reference (at least, I think this is the same...)

Re: [solved] kernel 3.6 does not recognize my pata DVD and CDROM

I don't think so... my error is totally different. Here's my whole dmesg
http://pastebin.com/L5h5rees

And these are the two snippets I think point out the issue

Re: [solved] kernel 3.6 does not recognize my pata DVD and CDROM

Ok, for me this is solved. Kernel developer Ben Hutchings answered:

I think what has happened is that pata_acpi has become more capable and so is able to bind to the JMicron PATA controller.  I would suggest disabling pata_acpi, as you would probably not want to use it even if it worked.

This means pata_acpi takes over when pata_jmicron should. Preventing the kernel from loading pata_acpi with the kernel boot parameter modprobe.blacklist=pata_acpi seems to solve my problems. I edited /etc/default/grub to include this to the kernel command line.

Note: putting this in an /etc/modprobe.d/*-file and regenerating initramfs does not work as the kernel seems to autoload this module.

Could you please verify this solution? I'll mark this as solved then.

Re: [solved] kernel 3.6 does not recognize my pata DVD and CDROM

Thanks a lot! Worked for me too.
Regarding blacklisting in /etc/modprobe.d, did you try the "install pata_acpi /bin/false" hack instead of the simple "blacklist pata_acpi"? I think it's necessary, because module libata depend on it, so the former would be pulled into system althoug the blacklist. Be aware that libata is dependency of scsi_mod at least, with /bin/false hack none of these two should be loaded. I think kernel parameter blacklisting is the better way.

I think so, too. Marking this as solved

Re: [solved] kernel 3.6 does not recognize my pata DVD and CDROM

Adding modprobe.blacklist=pata_acpi to the kernel line did not work for me, but I picked up a tip from the Ubuntu forums.

Someone suggested changing the ide cable for an older 40 wire type.

This worked, although I still get the acpi timing error warning at boot.

Re: [solved] kernel 3.6 does not recognize my pata DVD and CDROM

there is a better solution :

use kernel option :

libata.force=40c ( force UDMA 33 )

libata.force=   [LIBATA] Force configurations.  The format is comma
                      separated list of "[ID:]VAL" where ID is
                      PORT[:DEVICE].  PORT and DEVICE are decimal numbers
                      matching port, link or device.  Basically, it matches
                      the ATA ID string printed on console by libata.  If
                      the whole ID part is omitted, the last PORT and DEVICE
                      values are used.  If ID hasn't been specified yet, the
                      configuration applies to all ports, links and devices.

                      If only DEVICE is omitted, the parameter applies to
                      the port and all links and devices behind it.  DEVICE
                      number of 0 either selects the first device or the
                      first fan-out link behind PMP device.  It does not
                      select the host link.  DEVICE number of 15 selects the
                      host link and device attached to it.

                      The VAL specifies the configuration to force.  As long
                      as there's no ambiguity shortcut notation is allowed.
                      For example, both 1.5 and 1.5G would work for 1.5Gbps.
                      The following configurations can be forced.

                      * Cable type: 40c, 80c, short40c, unk, ign or sata.
                       Any ID with matching PORT is used.

                      * SATA link speed limit: 1.5Gbps or 3.0Gbps.

                      * Transfer mode: pio[0-7], mwdma[0-4] and udma[0-7].
                       udma[/][16,25,33,44,66,100,133] notation is also
                       allowed.

                      * [no]ncq: Turn on or off NCQ.

                       If there are multiple matching configurations changing
                       the same attribute, the last one is used.

Re: [solved] kernel 3.6 does not recognize my pata DVD and CDROM

Thanks for the tip.  This killed my system after upgrading, but the modprobe.blacklist=pata_acpi line worked.

Thank you so much. Had been looking here and there, trying this and blacklisting that, however that finally did the trick.
