Public bug reported:
The release of Ubuntu : 21.04 LiveCD, 20.10 also has this problem
What happened (How to reproduce):
Boot to liveCD 21.04 or 20.10 (before 20.10 bitlocker is not supported out of
the box )
Insert a bitlocker-protected usb flah drive, type in the password and the drive
will be mounted
Unplug the drive without clicking "Safely remove drive" to simulate an
unexpected disconnect
udisksd will crash immediately and never recovers unless you reboot the machine.
What you expected to happen
don't crash or recover without a reboot.
My usb flash drive is formatted by an old W7:
sudo cryptsetup bitlkDump /dev/sdd1
...
Version: 2
...
Cipher name: aes
Cipher mode: cbc-eboiv
Cipher key: 256 bits
...
dmesg output after the crash: (LiveCD, 21.04)
