Dear maintainers, I got into the same problem.
However, although I did not change anything, after a reboot the system hanged. It was not possible, to enter the encryption passwords for my partitions (/var, /home), as it jumped after a few seconds into the emergenmcy option ("type CTL D or enter administration password", you know what I mean. In emergency mode got the same error as described in the bug. However, commenting out the entry none /proc/bus/usb usbfs devgid=121,devmode=664 0 0 in /etc/fstab as Fabrizio Regalli (thanks for this!!!) found out, did the system let boot again. Is this entry not needed any more? Thank you for reading this. Best regards Hans
