Re: IO-APIC on nforce2 [PATCH]

[Christian Kröner]

since its becoming fancy to post dmidecode output, here is mine. my bios 
vendor is MSI (K7N2-Delta) and it has released many BIOS updates for this 
board, but none of them fixes the timer-issue. i only got the timer issue, 
(related with it the already discussed obscure hi-load) no hang with c1 
disconnect enabled. another thing i recently noticed (running 2.6.6-rc2-mm1 
now) is that the last XT-PIC interrupt is gone now. i had cascade on irq2 
routed as XT-PIC before, now cascade (whatever it is) doesnt exist 
anymore ;).

/proc/interrupts now:

  0:   32184529    IO-APIC-edge  timer
  1:       1741    IO-APIC-edge  i8042
  7:          0    IO-APIC-edge  parport0
  8:          4    IO-APIC-edge  rtc
  9:          0   IO-APIC-level  acpi
 12:       9229    IO-APIC-edge  i8042
 14:     107111    IO-APIC-edge  ide0
 15:         92    IO-APIC-edge  ide1
 16:       3138   IO-APIC-level  ide2, saa7134[0]
 17:        153   IO-APIC-level  CMI8738
 19:    2732391   IO-APIC-level  nvidia
 20:    4315754   IO-APIC-level  ohci_hcd, eth0
 21: 1167427697   IO-APIC-level  ehci_hcd
 22:         79   IO-APIC-level  ohci_hcd

another thing that bugs me a little (a little offtopic here maybe), is the 
irq21 of ehci_hcd seems to get hit about twice as often as the timer irq 
although im not at all using USB...   any suggestions? maybe i start a second 
thread on this one...
