Hello! I don't know if it really belongs to this list, since i have only tested on 7-CURRENT, but on the other hand 7-CURRENT is soon going to be stable. So here it goes: 1) insert usb flash disk 2) usbd detected it 3) mount it (mount -t msdosfs /dev/da1s1 /mnt) 4) simply pull the pen drive off the usb slot 5) /mnt mount pount is left 6) try to unmount it (umount /dev) I don't know to get all those kernel bright white messages in to a file, so i just attached a screenshot ;) -- Regards Artem

There was a *very* long discussion about this behaviour and how to solve it. It's not specific to USB devices either. The bottom line is that solving this issue is not easy, and that administrators should remember to unmount before pulling a device.
