This is intentional because some drive might be failed to be proved after bus reset. To prevent detaching mounted filesystem, it's not detached at first bus reset. After several bus reset it will notify to the SCSI layer. Try 'fwcontrol -r' several times or don't worry about it too much :-) This behavier enables us active filesystem detaching and reattaching. Even while the some process is writing/reading activily on the filesystem it sould be safely detached and then reattached safely. If your drive doesn't have important data, try detach and reattach while running 'iozone -A' :-) > If I try a 'camcontrol rescan' it hangs in cbwait (not sure how long, > but I left it for >30 minutes with no change).

Do you have traceback? which malloc caused panic? /\ Hidetoshi Shimokawa \/ simokawa@sat.t.u-tokyo.ac.jp PGP public key: http://www.sat.t.u-tokyo.ac.jp/~simokawa/pgp.html To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
