This seems to help, at least for > the limited things I use this pen drive now. I'm not sure, that this g_vfs_done is related to the panic. I've attached the drive to an uhci drived port on the same machine, started an fsck and I've got an immediate panic: trying to sleep while sleeping is prohibited If I remember it correctly. The driver has some power saving feature which shuts the drive down if it is not used for some time and spins it up when a request arrives. But yesterday I powered the drive up... waited some secunds and started then a fsck. So I guess it was not in a "shutdown" state - So I wonder who requested a sleep ;) -- Oliver Lehmann http://www.pofo.de/ http://wishlist.ans-netz.de/ _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd.org"
