Robertek, I still cant get git kernel working.
i have y entry iin grub like

title  Arch zen-eee
root   (hd1,1)
kernel /boot/zeneee-git root=/dev/disk/by-uuid/XXXXX_XXXXX_XXXXXXXX vga=788 ro
initrd /boot/kernel26.img

and getting kernel panic. but when i delete "-git" while bootingand boot old zeneee kernel it works - so everything in this grub entry should be fine

1) try change to root=/dev/sdb2  (I think you use that partition, am I right)

2)  remove vga=788 for now (It works for me but who knows:) )

When exactly it panics??

It looks like it would not be too diffcult to compile a custom video driver kernel module for the eee 901.  It really starts to get interesting around post #5.

i followed choris litle howto and it works now smile but still without sound.

$ alsamixer
alsamixer: function snd_ctl_open failed for default: No such file or directory
$ amixer
amixer: Mixer attach default error: No such file or directory

do i have to load any special modules? in wiki is written it should work out of box
and is this kernel using oss or alsa?

Re: Arch on Asus EEE 901

OK i got the wlan switching to work. But Suspend doesn't work at all, has anyone configured it to work?

Also is there a way to map one of the function keys (the silver ones) to change the speed of the processor or the powermodes?

Alsa is compiled into the kernel, you shouldn't need to load any modules.

What is the output of this command:

$  cat /proc/asound/version

and do you see anything like this in your dmesg output?

ALSA device list:
  #0: HDA Intel at 0xf7eb8000 irq 16

And finally, what is your MODULES list in /etc/rc.conf?  it should be very minimal, mine is only this: 

MODULES=(eee rt2860sta)

Sorry for that I forget to mention. I have now compiled the module for sound, for compatibility reasons with other kernels!

I have now a lot of work to do, so sometimes forget for something, apologise:)

Updated the wiki.

Try running

sudo /etc/acpi/wlan.sh poweron
cat /proc/acpi/asus/wlan (should return 1)
lsmod (rt2860sta loaded)

sudo /etc/acpi/wlan.sh poweroff
cat /proc/acpi/asus/wlan (should return 0)
lsmod (no rt2860sta there)

If that doesnt work, look into wlan.sh and do all the steps in poweron and poweroff separately.

yup these commands works but while pressing Fn+F2 only - WLAN OFF - is shown.. i have tried add it into eee.conf as additional commands after wlan is toggled but without succes. maybe i should have something like button-wlan in /etc/acpi/events ?

Version is the same a the compiled in, it is in git and will be in stable (I'll change git to stable when 27 is released, I dont use stable now, because of wlan switch)

Re: Arch on Asus EEE 901

@Robertek,

Nice fast boot on zen kernel...I like it.  One question I have though.  The eee-kernel901 has fuse built in and the zen-eee901 kernel does not.  If I were to be switching back and forth between these kernels just doing some comparisons, I have to enable/disable fuse in rc.conf.  Can you build fuse into the kernel or do not enough people use it?  I go to a university that has file space for students that is accessible off-campus.

I can just modprobe fuse if I really need to.

fuse is there. Maybe you should do the trick mentioned few post above.

I will look at it an maybe I will distribute zen-eee with its initrd.

Re: Arch on Asus EEE 901

Thanks for all the work, Robertek et al.  I now have Arch running on my 901.  It feels much more homey than Xandros did.  smile

One question.  How do you guys keep log files relegated to RAM to minimize SSD writes?  I currently have a 1M tmpfs on /var/log, as the wiki suggests, but it fills up quickly with more verbose programs (like Samba), and some daemons tend to hang while waiting for a write(2) to complete when the diskspace runs out (eg, acpid).

I'd like to have a little bit of logspace, but don't want to give up much ram to a tmpfs.  Any suggestions?  It'd be cool to have some sort of ring-buffer filesystem that performed similar to the one used for dmesg.  When new data comes in, it throws out old data to make room.  I've no idea how this would work under the context of a filesystem, but it'd be a neat idea.

Cheers.

Add logrotate to cron.hourly, for example

I dont think so, because sometimes I do some upgrades and repairs beside PGKBUILD. And cloning git kernel is not so nice for all the people. (~250MB of small files)

I dont want to maintain two same things (I know that one of it will start obsoleting).

I will even stop maintain stable kernel to the time when 27 is released, becase for now everyone should use git version. (it is stable enough)

Re: Arch on Asus EEE 901

I'm having trouble getting a LUKS filesystem setup using Robertek's zen kernel.

[root@pico proc]# cryptsetup luksFormat /dev/loop/0

WARNING!
========
This will overwrite data on /dev/loop/0 irrevocably.

Are you sure? (Type uppercase yes): YES
Enter LUKS passphrase: 
Verify passphrase: 
Command failed: Failed to setup dm-crypt key mapping.
Check kernel for support for the aes-cbc-essiv:sha256 cipher spec and verify that /dev/loop/0 contains at least 133 sectors

[root@pico proc]# lsmod | grep dm
dm_crypt               10884  0 
dm_mod                 40368  1 dm_crypt

[root@pico proc]# zcat config.gz | grep -i aes
# CONFIG_SND_MAESTRO3 is not set
CONFIG_CRYPTO_AES=y
# CONFIG_CRYPTO_AES_586 is not set

Anyone else?  Is the aes-i586 module required for this?

TIA.

@Robertek, just tried the new zen-eee901-git kernel and I'm still getting modprobe errors trying to load the modules.dep file.  I even tried rebuilding the image and it's still got problems.  Suggestion?

@Robertek,

Could you add other powermanagement modules than the ondemand? Atleast the Powersave would be nice to have
