Unfortunately, this is exactly the problem I sometimes face. If
network is up, then suspend works normally. But if network is down
(and I'm trying to access sshfs filesystem in that moment), then
suspend doesn't work.

So, it seems your solution is not for me

Okay, I will probably forward this to sshfs devs
