I'm seeing what I think is the same issue. I've got a 2tb WD drive with
btrfs. When I mount the drive, then unplug the usb cord connecting the
hard drive without first unmounting it, it presents an error then or
when I attempt to unmount the location that it is mounted under.
When the error comes up it appears as if the computer has crashed,
showing only white text on a black background similar to the linked
picture in the original message, however I can switch to a tty then back
to X and everything else seems to be fine.
After this I cannot mount the device again until after a reboot, as
mount will return:
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
If you want more information or for me to file this upstream I can do
so. Thanks.
