Re: [PATCH] i386: disable local apic timer via command line or dmi quirk

Thomas,

Is this failure specific to NO_HZ, and that is why the "nolapic_timer" fix is i386 only?
I'm running 2.6.21-rc5 an nx6325 here in 64-bit mode and I don't see the dramatic
boot failure described earlier in this thread.

However, I have observed that when running on battery,
the LOC falls behind the irq0 timer to the tune of about
2 interrupt/minute.  eg. when i booted my machine, LOC was
behind irq0 by 50, and now about a 20 minutes later it is behind
irq0 by 99.  However, the LOC for each processor remain at
a constant offset with respect to each other.

I do not see these this drift when running on AC.
Yes, the system exports just C1 in both cases.

Other oddities is the IRQ name on irq0 is garbled:
