What I did recently: Did a reboot (by using command `reboot') - the = system did not reboot on its own. All I got on the screen was: Syncing disks, vnodes remaining=859 2 2 2 1 1 1 0 0 done All buffers synced. Uptime: 14h58m19s usbus0: Controller shutdown uhub0: at usbus0, port 1, addr 1 (disconnected) ugen0.2: at usbus0 (disconnected) uhub4: at uhub0, port 1, addr 2 (disconnected) usbus0: Controller shutdown complete re0: link state changed to DOWN re0: link state changed to UP usbus1: Controller shutdown After waiting 30 minutes, I decided to power cycle the machine. After = reboot, the Zpool on the USB disk was not be able to mount because of a = missing label (the error message referred to = http://illumos.org/msg/ZFS-8000-5E). Thus, I had to destroy the zpool = and re-created it. I've copied lots of files to a ZFS volume on top of = the zpool and tried to reboot the machine. Got the same problem again. = Seeing usbub1: Controller shutdown but nothing happens. I see a relation = between the high interrupt rate and the USB device for some reason. = `zpool iostat 1` shows me that there are no read or write operations on = the device.= ___ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
