is that a threat?  ;-)

Try enabling sysrq, and do sysrq-t when it freezes, as a first pass, to
see where all the threads are (stuck) at.

You might also try this on a stock upstream kernel, and see if you have
the same problem with 8k stacks vs. 4k (as is in FC6)

You could also set up kdump and/or netdump (whatever FC5 supports...)
and get a system dump at the time it freezes up, via sysrq-c.

Thanks,

-Eric
