Have you been stress testing with debugging disabled? I was doing some
extreme testing and crashed reiser4 with this patch twice. The same test
that crashed it one of the times passes on reiserfs (didn't try the
other), and if enable debugging, I can torture reiser4 all night and
still not crash it. I'll do some more tests and try to identify a
simple, reproducible crash scenario.
