[Gigabyte EP45-DS3L] resume failure/corruption with 2.6.31 [regression]

[unggnu]

I am using the latest bios version and suspend/resume works fine in Jaunty and with Kernel 2.6.29 but it stops with 2.6.30 release candidates and still doesn't work in mainline final and of course in the Karmic version.

Sometimes in very rare cases resume works fine but normally the pc hangs completely (monitor output doesn't get activated), or I can't do anything except of moving the mouse or all disks are mounted read-only.

There should be enough information in the upstream report. I have tried bisecting but there seems to be more than one bad commit or it is more random than I thought.

It seems that now every time the kernel freezes after resume. Even the monitor gets no signal anymore. Probably since Kernel 2.6.31.
I have gathered the magic number and hash match with the Wiki DebuggingKernelSuspend howto.
I am using the recent Karmic version.

Changing back to Bios version F8 seems to fix the problem.

Hi, I too am affected by this exact same bug, but it's on my laptop rather than on a desktop.
