--- Comment #5 from higuita <higuita@gmx.net> ---
ok, more info.

I have spend half of the weekend to try to debug this with kernel 2.12.1 and
this is what i found:

in the bios if i disable both the "V-Link 8X Support" and "AGP Fast write",
things get more stable and i only have problems if i hibernate with the machine
with load (actually, i'm using the glxgears)

If i disable the "ACPI APIC", i have no problem at all, the machine is stable
during many hibernations cycles, even on heavy load... saddly, i lost the
second CPU without APIC

So i think this points to something related to the AGP bus.

With the APIC turn on and the "Vlink" and the "AGP fast write" turn on, i get
the problem even on the console, without the X11 loaded, so maybe the something
used by the modeset.

I will try to disable it and do some more test.

Again, i only have problems with hibernations, if i dont hibernate, everything
looks stable during several weeks/months
