I too was bitten by the bug. The damning part of this bug is that for users with MODULES="radeon" configured in /etc/mkinitcpio.conf, the bug hits just as the radeon kernel module is loaded by the initramfs 'which clears the screen' leaving you staring at a blank locked computer. Not much info to debug since no logging has been activated at the time. To fix the problem, as specified in the thread, just restore etc/mkinitcpio.conf to its original state by removing/commenting out the MODULES="radeon" line: # MODULES # The following modules are loaded before any boot hooks are # run. Advanced users may wish to specify all system modules # in this array. For instance: # MODULES="piix ide_disk reiserfs" #MODULES="radeon" MODULES="" and then add radeon to the modules line in /etc/rc.conf: MODULES=(radeon ath5k vboxdrv !pcspkr) Then upgrade the kernel and all will be good.

I loaded 2.6.32 tonight and the box hung right after the screen flashed (where it normally goes from big text to small text [i.e. changes resolution]) and the box locked up. I had to use the install cd to downgrade to 2.6.31-6 in order to boot again... -- David C. Rankin, J.D.,P.E.

Did you know you can append "3" to the kernel line in the boot menu of GRUB in order to boot in init 3? This would avoid loading X and could be useful for you. I have no idea what could be causing your problem, however. Sébastien Leblanc
[arch-general] Yikes! kernel26-2.6.32-1-x86_64 leaves Toshiba laptop unbootable
Guys, I had a fairly rude surprise when I pulled the testing updates tonight. The install of kernel26-2.6.32-1-x86_64 left my toshiba 205d laptop unbootable. The boot process would start as usual but then get to a point just after it had started X and lock. There was no way to ctrl+f1 to break out of X and the only solution was to reboot. I booted to the install cd, and chrooted everything in /mnt/arch and downgraded the kernel to kernel26-2.6.31.6-1 (along with madwifi) and now everything is back to normal. I have looked throught the logs, but I don't know where the useful information would be captured. I think the failed boot sequences (I tried twice) are shown in these snippets: kernel.log: Dec 6 20:55:46 alchemy kernel: Unpin not necessary for 88011dd6fe00 ! Dec 6 20:55:46 alchemy kernel: i2c-adapter i2c-1: unable to read EDID block. Dec 6 20:55:46 alchemy kernel: radeon :01:05.0: LVDS-1: no EDID data Dec 6 20:55:46 alchemy kernel: i2c-adapter i2c-1: unable to read EDID block. Dec 6 20:55:46 alchemy kernel: radeon :01:05.0: LVDS-1: no EDID data Dec 6 20:55:54 alchemy kernel: Unpin not necessary for 8800ba072800 ! Dec 6 20:55:56 alchemy kernel: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready Dec 6 20:55:56 alchemy kernel: wlan0: deauthenticating by local choice (reason=3) Dec 6 20:55:56 alchemy kernel: wlan0: deauthenticating by local choice (reason=3) I don't even know if the failed boot attempts made it to the point that logging was turned on. Anyway, you guys let me know what you want to see or what you want me to test and I'll get it for you FAST. I can't have my Arch install down. I can live without suse, but not Arch ;-) -- David C.

Hm, I hope you are happy this way until we know what's going on ... the problem is certainly not that the firmware is not put in initramfs, but something else ... something weird. FYI, not-so-happy radeon kms user here: http://bbs.archlinux.org/viewtopic.php?pid=667665#p667665 he'd like it earlier for plymouth. T.
