Hi, I'm also experiencing this bug. The process 'mount' is consuming 100% CPU; I cannot manually kill it as root nor reboot/shutdown the machine:
root 9661 99.9 0.0 18640 1052 pts/1 R+ 06:59 12:54 /bin/mount -t udf -o nosuid,nodev,user,async,atime,noexec,uid=1000,gid=1000,umask=000,iocharset=utf8 /dev/mapper/_dev_sde1 /media/hd The problem, which is always reproducible, starts when I try to mount a usb mass storage device (actually an external hard disk) through 'pmount' as: pmount /dev/sde1 hd I don't think the device is faulty, although I cannot ensure.
