On two of my amd64 machines (a desktop and a laptop), I have been plagued, for several months, by seemingly random high system loads (100%). Sometimes after a few minutes, sometimes after a couple of days, of use, my CPU useage would effectively hit 100%, with top showing 2 CPU cores hitting 50% each on "system".
For some time, I could not work out any way of solving this, short of rebooting the machine in question. It now seems that the culprit is gkrellm: killing it reduces the "system" load back to down to 0-3%. Has anyone else seen this problem with gkrellm? I'm at a bit of a loss to explain why it happens so randomly. It might, perhaps, be related to the rthreads transition, but it's hard to be sure. The laptop dmesg is attached at the end. If anyone wants further details, I'm happy to provide them.
