--- Comment #16 from Cristian Rodríguez
Wow, interesting.
Not sure, but it could have to do with these dmesg lines:
drm: registered panic notifier [Firmware Bug]: ACPI(PEGP) defines _DOD but not _DOS
This persists.
APIC error on CPU0: 00(80) : Illegal register address APIC error on CPU0: 80(80) : Illegal register address
This messages have gone away in recent kernels.
acpi device:2e: registered as cooling_device4 video: probe of LNXVIDEO:00 failed with error -5 acpi device:32: registered as cooling_device4
Iirc you already put acpidump somewhere, can you attach it to this bug as well, please.
OK, Will upload it later .
probe the LNXVIDEO:01 and whether the machine is stable then (and the APIC errors do not show up) and backlight still works, etc.
I am using just one of the video adapters.. the intel one .. and the backlight works just fine.
I could imagine there is an access to an APIC register which is not allowed in X2APIC mode
Yeah, I think we are near the root cause here.. ;) however it is *very* hairy to sort out and get consistent behaviour.. I would love to be able to make the kernel panic when stuff goes wrong, however I just end up with early hangs at random points ;( -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
