--- Comment #11 from Cristian Rodríguez
Also toggling this kernel option OFF: config IRQ_REMAP ... workarounds the problem... Have you compiled it out or have you just used the boot param intremap=off ?
Both.. booting with intremap=off says: "Enabled IRQ remapping failed" (or something similar I do not have the exact message in memory) When compiled without IRQ_REMAP It does say nothing about IRQ remapping.
That's weird or say a good finding: Booting with nox2apic also enables interrupt remapping: Enabled IRQ remapping in xapic mode (cmp. with your logs/dmesg in your snd attachment).
Yes, It goes into "legacy xapic" mode (according to the somehow convulted intel docs)
The logs there have some nice debug output. If it's somehow possible to get a failing boot with these "apic=debug acpi.debug_layer=0x400000 i8042.debug debug"
I already try that, even built the kernel to panic on soft/hard lockups, oppses, lockdep debugging etc.. and acpi either does not say a word and "hangs" without message, OR it continues booting with non-functional keyboard/touchpad, once I plug an external keyboard, I can use the system but without wifi @_@ .. as the Intel ucode for the iwlwifi driver fails to load... (that is extremely weird, because if I remove the driver, wait a few minutes and reload again, it works...)
as well, we would have something we can compare good vs bad in detail.
This could get a very nasty one.., I try to get some time for it, but as there is a workaround (nox2apic) and my queue is rather filled right now, it may take some time for the one or other answer.
No hurry, I have not yet seen any negative effect of the workaround and constantly checking for BIOS updates as I'm more and more convinced this is a BIOS bug. -- 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.
