Kernel panic. Fallback doesn't run either.

goetzkluge · 2010-05-09 19:16:51

I run upgrade with packman -Syu today, then rebooted. Kernel panic!

Also fallback doesn't work. So I cannot run anything. I still got an old Mint Linux and probably have to use that to repair Arch.

The upgrade was today 21:00 UTC. My last upgrade was yesterday.

toffyrn · 2010-05-09 19:23:10

Mount arch-partition from Mint, and have a look at what packages was upgraded.

Perhaps you can solve it by a downgrade?

> Mount arch-partition from Mint, and have a look at what packages was upgraded.

Thank for the help. Can you tell me where I have to look? And then I do not know, how to downgrade if I can't get pacman running.

The startup goes up to here:
...
...
::Starting udevd ...
done
AT Translated Set 2 kayboard as /devices/platform/i8042/seriaeio0/imput/input1
/init:export: line 52: [some garbage] : bad variable name

Then Kernel panic.

hokasch · 2010-05-09 20:02:50

log files are in /var/log, to downgrade packages from linux mint you have to chroot into your arch install (check the kernel panic wiki page). sadly I have no idea what that message could mean.

Andrwe · 2010-05-09 20:28:56

Please list your params of your kernel line.
If there is any using a . then you have to find remove this one.
I've encountered this issue with radeon.modeset=1 there I had to remove radeon. and then it worked.
It seems to that the new init-script isn't replacing dots correctly or maybe there are cases the dots shouldn't be replaced but I don't have much knowledge about the init.

finarfin · 2010-05-09 20:40:11

I have the same problem.
Archlinux-Fallback run without problem.

I tried to downgrade:
kernel at 2.6.33.3-1
kernel-headers at 2.6.33.3-1
kernel-firmware at 2.6.33.3-1
mkinitcpio at 0.6.3.1
mkinitcpio-busybox at 1.16.1-1

but without luck!!
Plz help me

Initscript are involved in generation of initrd?

P.S. sorry for my bad english

signor_rossi · 2010-05-09 20:46:36

I am affected by the same bug, fortunately fallback still works. I recall that I had strange garbled fonts in Xorg too before the upgrade, I still could recognize that there was a kernel update available so I upgraded to see if that would solve that issue but then on reboot I got the kernel panic. Gonna change the radeon.modeset=0 entry to modeset=0 in grub now and reboot and report back.
BTW, with kernel 2.6.34 there (hopefully) will be power management support with KMS, so I can finally enable it again.

wonder · 2010-05-09 20:47:32

update mkinitcpio-busybox to 1.16.1-3 and rebuild kernel images with mkinitcpio -p kernel26

signor_rossi · 2010-05-09 20:53:37

Changing the radeon.modeset=0 entry to modeset=0 worked for me. Does modeset=0 even do anything anymore?
Will do as wonder advises too.
BTW, to those with problems, you can edit the grub command line on bootup, so maybe you can get into a working system doing so.

goetzkluge · 2010-05-09 20:56:51

Thanks Andrwe! I am back with Arch. I removed "radeon."
(Small issue (but I'll handle it): The console now starts with very small fonts.)

This is a very helpful community. Thanks again, Andrwe.

Best regards from Munich
Goetz

@wonder
but upgrading to new mkinitcpio i can use readeon-modeset=0 in grub?

Btw: removing radeon-modeset without re-run mkinicpio, the problem disappear.

finarfin · 2010-05-09 20:59:46

Is it a good idea to open a bug for that problem?

Thanks to Wonder in IRC for the advice given that they also shared above. FWIW discussion in IRC mentioned a bug with kernel line options containing "." that caused the panic, see here:
http://bugs.archlinux.org/task/19403

goetzkluge · 2010-05-09 21:25:26

FYI:

Previously I had to use radeon.modeset=0 in order to avoid trouble.

I think, there some improvement had been implemented, because I could remove modeset=0 and now the boot still runs fine. (Perhaps the Kernel ignores modeset=0 anyway.)

(As for the small console fonts, for the time being I'll use spectacles...
I guess, there somewhere is some radeon.xxx parameter, where I can disable the radeon mode which uses these small fonts.)

X runs fine.

Thanks to all of you
Goetz

After pacman -Syu
last version of mkinitcpio-busybox is 1.16.1-2 is affect with that bug, also after last pacman -Syu (few minutes ago).
I see from site that latest version in core is 1.16.3, so my mirror has some lag?

goetzkluge · 2010-05-09 22:49:33

Seemingly the radeon.modeset=0 had some purpose: Now X crashes sometimes, e.g. once I click on the "Options"-button in Firefox, which appears in the lower right corner for NoScript-operations.

Thanks, i removed "radeon." too and all works fine, till now.

bastardo · 2010-05-10 16:10:41

Yep, removing the radeon.modeset=0 of course enables radeon modesetting leading to the high resolution in terminal.
On R600 it also lead to the renumbering of outputs (comparing normal userspace driver and KMS) and disabling of xvideo.

I think this should not only be reported as a bug, but also on the frontpage. Otherwise just release another dummy kernel package, so that the initcpio gets rebuilt automatically.

Best,
Basto

dany13 · 2010-05-10 16:51:35

I confirm that with . in the kernel line it is giving kernel panic, even i915.modeset=1 is giving the same trouble.
I agree with frontpage reporting.

Best regards.

goetzkluge · 2010-05-10 20:07:26

I removed radeon.modeset=0
Then edit (or to create) /etc/modprobe.d/radeon-kms.conf and insert the following line:

options radeon modeset=0

For me now everything runs fine.
