Hi,

Somewhere between:
03347e2592078a90df818670fddf97a33eec70fb (2.6.30 + 5415 commits)
and
c82e6d450fda56cb2d4f68534173d3cd11b32f9f (2.6.30 + 8722 commits)
my Laptop (Lenovo T500) with an Intel GM45 graphics card blanks display
during boot (before starting with initramfs) , stops responding to
anything (i.e. no caps-lock light) and shows no further activity (i.e.
no hdd activity).

Before the blank I did not see any sign of a backtrace or similar, but
its hard to say there wasn't any. Unfortunately atm I don't have another
computer nearby, so I could not get a network console output yet.

If you don't have a quick idea I will either get nearby another computer
to get a trace or start bisecting.
I have not yet had access to another computer (so no trace yet) but I bisected it to this very innocent looking commit:
1e4cffe78e1decd937c7b78410eec87da6b87954 : ACPI: video: convert to acpi_get_pci_dev

Hope I added the correct CC's

Andres

PS: bad Headache + no tiredness is a good combination to do bisecting ;-)
