Hi...
I reported this before but not as detailed, so maybe someone knows to
deal with it...
This oops is still within the kernel it happens at least since ac18 and
did not under ac10 (at least not that reproducable at boot time!!!)
Reproducable even when booting with init=/bin/sh
by doing: ls -R /proc (proc mounted)
ps auxw tells something about much cpu time kapmd uses (hmmhhh)
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND

If you need further infos... I do my best...
Soeren.
