Hrm, Vassilis seems to be able to reproduce this more effectively by heating up his CPU prior to hibernation though. I have no idea what adding APIC_LVT_MASKED ((1 << 16)) to the Local Vector Table (LVT) Thermal Monitor (APIC_LVTTHMR 0x330) does but clear_local_APIC() seems to be used to "cleanout any BIOS leftovers during boot." If we're suspending but the fan is still on I wonder if this could cause an issue with some settings the BIOS may have set prior to hibernation, and a mismatch upon resume. I can't find what APIC_LVT_MASKED does though, the best doc I found: https://www-ssl.intel.com/content/dam/www/public/us/en/documents/white-papers/cpu-monitoring-dts-peci-paper.pdf The inability to set the MTRR for the i915 card might be totally separate issue at this point, not sure. One could test that I suppose by just using vesa graphics card driver (disabling i915) to at least get a basic screen to see things and compile/test things.
