I have several OK 12.3 x64 machines running, and suddenly on one of them, 100% of a single core is being used by something called kipmi0 - I've been searching the web and it's sort of obscure. I've tried forcibly killing it, and it instantly reappears. Why on this machine? Is it related to some BIOS setting? I didn't find any references on this forum either... Does anyone have more information that might help me recover that CPU time?

Thank You!!
