Oh, a fedora kernel.  I received some reports that fedora kernel
changelog claims to have the event cache fix, but in reality it is not
applied. =20
People who switched from fedora to a current git kernel have reported
that the problem has gone away.

Anyway, the bug report from the link above talks about=20

Call Trace:<ffffffff88308c29>{:ip_conntrack:ip_conntrack_cleanup+20}
       <ffffffff88306ab4>{:ip_conntrack:init_or_cleanup+676}
       <ffffffff80157798>{sys_delete_module+490}
       <ffffffff801118aa>{syscall_trace_enter+217>
       <ffffffff8010eb6c>{tracesys+209}

which seesm to have no relation to the event cahce, but rather some
module unload problem. Are you sure that bug report is the right one?

mh, I could try that since I'm having a Turion64 notebook... but never
had the idea to run an smp kernel on it.
