Package: udisks2 Version: 2.1.8-1 Severity: important Dear Maintainer,
on my system with Samsung 970 Evo M2 SSD, the command udisksctl "power-off --block-device /dev/sdx" causes a complete system freeze. Input devices are not responding, only hard reset is possible. Logfiles report series of null bytes only (syslog, messages, even jounalctl -f). The problem occurred after installing a new system on a M2 SSD. The problem does not occur using my old (quite similar) system, installed on a SATA SSD (Samsung 850 Pro). It does not depend on which kind of USB device (HDD or pendrives) is powered off. The power-off is successful before the system freezes. (though nothing is recorded in logfiles) The only way to avoid the freeze is not using the command (and the thunar filmanager unmount feature using it). It may be a hardware problem, but other users have similar problems.
