Sorry for the missing information.

Yes, this is a Mac mini Core Duo with a i945 chipset. The crash happens
with the 2.1.1 as well as with the recent git version from the 2.2
branch.

No, I use the hibernate script from the TuxOnIce project to suspend to
RAM. This doesn't use HAL at all.

Hum, I recently started to use vbetool to restore the VBE state after
resume, otherwise the text console stays blank after resume. Maybe this
is connected. I see that there is also an "VbetoolPost" option in the
hibernate script, that isn't enabled. I'll enable it to see if it
helps.

Thanks for the hint.
