Hi,
    I think the new patch still have some problem.I run zfs on my 
laptop,and it panic on zfs umount.
    The problem ( http://www.freebsd.org/cgi/query-pr.cgi?pr=124200 ) 
relate  to zfs? It alway panic in spa_zio_intr_1 and txg_thread_enter. 
Benjsc is working on it.If any one interest in problem 124200, you can
