------- Comment #8 from jan.fikar@psi.ch 2008-04-11 04:32 -------
I'll try...
I'm not sure about APIC error, as some kernels before (till 22 or 23 if I
remember well) the log was full of those APIC errors. They were produced at a
speed of two or three per hour. And I thought they are harmless. Anyway at that
time there were no problems with atiixp.
Then with the 22 or 23 upgrade they do no come so often. Maybe once per day or
so and I still ignored them. In fact I'm not sure it was corrected or only
silenced. There were still no atiixp problems. The atiixp timeouts started in
24.
I think I can check your hypothesis, maybe you are right. I remember that at
least in the 2.6.25-rc6 case with the single DMA timeout the APIC error was in
the log just before. However I'm not sure how long before. I think I can switch
on the timestamps.
And if it really is an IRQ routing problem, shouldn't I try to disable it by
noapic kernel parameter or something like that?
