You should apply ftp://ftp.namesys.com/pub/reiser4-for-2.6/2.6.14-rc4-mm1/reiser4-fix-livelock-2.patch and then ftp://ftp.namesys.com/pub/reiser4-for-2.6/2.6.14-rc4-mm1/reiser4-spinlock-cleanup-2.patch to clean 2.6.14-rc4-mm1.

If your filesystem load encounteres lockup - you should try to set REISER4_USE_EFLUSH to 1. If that does not help - please report the bug.
