PS. And also have we have strange bug in another computer (2.6.22-r5).
Have computer XEON_CPUx2 (4 CPU)
after boot have CPU0 and CPU3 SI = ~50%
after some time CPU0 SI = 0% and ksoftirqd/2 process have 100% cpu usage!
nat-new ~ # cat /proc/interrupts
CPU0 CPU1 CPU2 CPU3
0: 403 0 0 0 IO-APIC-edge timer

LOC: 89312505 89314019 89310139 89313972
ERR: 0
MIS: 0
changes only LOC interrupts!
Maybe its info intresting for you. =)
Yes. It seems something loops or breaks with disabled interrupts. If
On the other hand disabling local interrupts shouldn't be enough here,
so it's really strange... Did you get this remotely? Are you sure LOC
only? (Anyway this 2.6.23-rc4 should be interesting.)
Jarek P.
Only LOC changes... icmp answer = 50-70ms... after 1-2 hours traffic
level is down and SI on CPU0 and CPU2 change to above 50%. ksoftirqd
free CPU usage. I have this bug 3-4 times in week. If you need info what
i can see only in bug still processing - i may try get this info for you.
maybe help:
