Bugzilla Bug 126051

Hello.
I have Dell 600m with a Radeon Mobility 9000M video card. I am posting this
here because my BIOS will not POST the video card upon S3 resume, so this is
instead accomplished by a gentoo patch to the radeon driver. Maybe someone here
will be able to figure out what the heck is going on.

Basically, on kernel 2.6.12 and up (right now I am on 2.6.15) the machine will
lock up (no HD activity, no backlight, nothing) during resume from S3 suspend.
On kernel 2.6.11, this does not happen - the machine can go on
suspending/resuming for months without problems. However, 2.6.15, it locks up
during resume about once a week.

There is more detail and lspci output, etc, on Kernel Bug 5555:

I doubt the radeon patch is to blame for this, but you never know. Does anyone
have a clue as to why this is happening?

Thank you

Will watch upstream bug
