I got the "RCU detected CPU 1 stall" message in dmesg today. What does 
it mean?

The kernel is 2.6.33-gentoo-r1 (which contains 2.6.33.2.patch). I think 
that there was nothing active except torrents at that moment. Full dmesg 
and config are attached. I have not tried to reproduce the problem again.
