dmesg-2.6.36-rc4 (cmd line: root=/dev/sda2 hpet=force)

I have a Dell Inspiron 600m laptop with a radeon mobility 9000 card.
Kernel v2.6.36-rc4 compiled with KMS support produces a hard freeze on boot if I use a video= boot option. I see this also with kernel 2.6.36-rc1 but not with 2.6.35.

This is the kernel command line that makes the kernel freeze on boot:
root=/dev/sda2 hpet=force video=1024x768-24@60

The kernel boots fine with this command line:
root=/dev/sda2 hpet=force

I attach a dmesg captured after booting without a video= option.
Comment 1 Jose Marino 2010-09-21 20:01:09 UTC
The problem disappeared with kernel 2.6.36-rc5.
