> 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.

Thomas, Gabriel:

	Thank you for the solution in the thread "[arch-general] Kernel 2.6.32 and Radeon KMS". 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. Thanks again for you guys help!
