[Bug 567412] [NEW] Regression: system cannot start with kernel 2.6.32-21

[Pavel Borecki]

Public bug reported:

After update from linux-image-2.6.32-20-generic to -21 version on Lucid
beta2, system is no longer able to boot. Maybe it is graphic card driver
related issue.

Normal operation with kernel version -20: normal splash screen with
prompt for decrypt root fs (i am using dm-crypt/luks), then GDM and etc.

Wrong operation with kernel version -21: deformed splash screen with
prompt for decrypt (see screenshot), then (after successful root fs
decrypt) computer freeze totally - screen is black (backlight is on)
keyboard is not responding (Caps, Num, Scroll lock), no harddisk
activity, etc. I must turn it of with hw power switch.

I tried to start without quiet and splash kernel boot parameters -
system froze during transition between text and graphical mode. Disable
KMS with nomodeset kernel boot parameter did not change anything.

Unfortunately, there are no records written into log files during
unsuccessful boot.
