So, this looks like a drive firmware bug. You >>> should contact Dell to find out if newer firmware is available for your >>> drive. In the mean time, you can try lowering the tag depth allowed >>> for your device. If the failure occurs sometime after rc processing, >>> you can make a call early in the transition to multi-user like so: >>> >>> camcontrol tags da0 -N 64 # or some lower number >>> >>> If that won't work for you, you can enter a quirk into >>> sys/cam/cam_xpt.c >>> or just modify the last quirk entry (the default) to have a lower tag >>> depth (it is currently 255). >>> >>> If you do get new firmware for your drive and that resolves this issue, >>> please follow up to the list (and cc me if you don't mind) so that >>> others that encounter the same issue can benefit from your experience. >>> >>> -- >>> Justin >>> >> >> _______________________________________________ >> 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" > > > -- Ronald Klop Amsterdam, The Netherlands
