Me too. Dual PIII, 2.5.34+localhacks. It's happened a couple
of times. The system locks up and the CPU fans go nuts. In X, so
no info available.

There are a few locking problems in 2.5.34 which _may_ be fixed
now, but they only seem to affect CLONE_THREAD. It would be worth
grabbing the latest `gzipped full patch' from
http://www.kernel.org/pub/linux/kernel/people/dwmw2/bk-2.5/
though.
