[pkg-cryptsetup-devel] Bug#1109612: cryptsetup-suspend: Stuck trying to suspend with certain processes running

[Huey Chen]

Package: cryptsetup-suspend
Version: 2:2.8.0-1
Severity: grave
Justification: causes non-serious data loss
X-Debbugs-Cc: hueychen27 at outlook.com

Dear Maintainer,

Some processes, such as running timeshift, rsync, or another I/O intensive process, cause suspending with cryptsetup-suspend to be stuck while attempting to suspend. Even after waiting over 12 hours, the screen will not turn off
and cryptsetup-suspend still tries to suspend the system. All I can see is a black background with system messages, one of them stating how the system is suspending, and all I can do is type characters.

That forces me to forcibly turn off the system, leading to potential data loss when running the intense process.

I expect cryptsetup-suspend to suspend normally in a timely manner, even with such a process still running.

Perhaps this is an issue with suspending in general?

Sincerely,
Huey Chen
