Re: Fwd: Re: Working nforce2, was Re: Fixes for nforce2 hardlockup, apic, io-apic, udma133 covered

[Craig Bradney]

Just to give the status here ...
Im still running the original 2.6 test 11 patches for apic and ioapic.
Uptime is now 2d 20h with lots of idle time and hard work too.. 

/proc/interrupts as follows:

           CPU0
  0:  245382420    IO-APIC-edge  timer
  1:     139577    IO-APIC-edge  i8042
  2:          0          XT-PIC  cascade
  8:          3    IO-APIC-edge  rtc
  9:          0   IO-APIC-level  acpi
 12:    1478615    IO-APIC-edge  i8042
 14:    1055548    IO-APIC-edge  ide0
 15:     737664    IO-APIC-edge  ide1
 19:   18405692   IO-APIC-level  radeon@PCI:3:0:0
 21:    5257090   IO-APIC-level  ehci_hcd, NVidia nForce2, eth0
 22:          3   IO-APIC-level  ohci1394
NMI:      14944
LOC:  245087891
ERR:          0
MIS:          6

As for NMI.. I actually forget which I booted from... I think =1, but NMI is a small number now.. would it have wrapped?
