Hello,
I've upgraded from 2.6.32-042stab133.2 to 2.6.32-042stab138.1 and since
boot, 2 cores are using 100% cpu on ksoftirqd:
root 21 99.9 0.0 0 0 ? R May29 1178:07 \_
[ksoftirqd/4]
root 25 99.9 0.0 0 0 ? R May29 1177:51 \_
[ksoftirqd/5]
>From /proc/interrupts I can see that it's caused by IR-IO-APIC-edge

Any way to troubleshoot this? Is it a known issue?
