Sorry the information wasn't very concise. I am running SUSE 10.1 RC1.
During install it was very, very slow, which may or may not be a
related issue (worth mentioning in case). I do not think it is related
to nvidia but again, wanted to add it to show what I had tried.
The process that is taking up 90% of the CPU is called events/0. There
is an events/1 process that has 0% of the CPU...I'm not sure what
these processes do but I think they are processor related or perhaps
acpi.
