https://bugzilla.kernel.org/show_bug.cgi?id=65671 --- Comment #5 from higuita <higuita@xxxxxxx> --- 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 -- You are receiving this mail because: You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
