Cinnamon 5.0.5 Mint 20.2 64bit

I'm not able to reproduce this issue. Restarting from Suspend does crash Cinnamon and resumes the session as expected.

I had this same issue and can reproduce it easily. It happens only in just one out of seven test systems (Ghia Frontier PCGHIA-2546 (Desktop), Rizen 5 2400G, 64bits, 32 GB RAM) and only if Hybrid Sleep is enabled. If this feature is disabled, Cinnamon suspends perfectly without any issue.

Hybrid suspend is known to be very buggy and is usually disabled by default in many Linux distributions.

Thanks @darkshram ; I've disabled Hibernation, and we'll see how it goes now.

FWIW, I'm using an Intel NUC box:

For me issue was solved by disabling 'Hybrid Sleep'. Again, 'Hybrid Sleep' is disabled in many Linux distros because is buggy an unreliable with some hardware combinations.

[wujastyk]

That would be nice, but I don't see the same options:

[darkshram]

@wujastyk I'm not using Linuxmint, and my OS does not use SystemD. But you may try:

sudo systemctl mask hybrid-sleep.target

Also, check: https://www.tecmint.com/disable-suspend-and-hibernation-in-linux/

[wujastyk]

Thank you @darkshram, those are good leads. I have, though, tried both approaches but with no success.
I get Cinnamon crashes too when I use Zoom, and in other circumstances where I can't see a common thread. I get about two or three per day at the moment :-(
