Title:
CIFS remote shares freeze on resume after suspend
Status in cifs-utils package in Ubuntu:
Confirmed
Bug description:
After resuming session from a suspend on my Dell XPS 13, any
previously remotely mounted CIFS shares are non-responsive, lock the
terminal on attempts to interact with the associated directories in
any way (tab complete, cd, ls, etc.). In system logs, I see the
following:
