high interrupt level
Hello, A Dell Poweregde 1850 constantly spents about one third of its time in interrupt 16. This box has run for a year without this issue. It has an almost generic kernel, only quotas are compiled in. Rebooting (without ipmi) does not help nor updating; the issue was already present before updating to 6.4 p1, but persists. The software hardly changes, except that ipmitool is recently installed to monitor temperatures. I tried to replicate the issue by loading / unloading the ipmi kernel module on a similiar box, but running 7.0-RELEASE-p7 . This does not lead to any problem however. Any pointers would be appreciated. It might not at all be related to ipmi, but I suspect it to be cause since it is the only change and I loaded a kernel module for it.
