suspend doesn’t work most of the time

Hi! I’ve been having trouble with suspend ever since I updated to 10.4. (IIRC 9.10 worked OK.)

When I click suspend, things start as normal: the screen goes dark after a few seconds. After a few seconds more, the screen goes to text mode; there’s a cursor blinking in the top-left corner. It stays like this for 20–30 seconds, then a message flashes for an instant, and then I get the password prompt from the screensaver (just the blank screen, actually).

This happens almost every time at the first suspend attempt. Most of the time if I try again it works, but sometimes it takes more tries. (More often I give up and just shut down.)

Today I managed to capture the message on camera:

***************
[24591.910011] Freezing of tasks failed after 20.00 seconds (1 tasks refusing to freeze):
[24591:922041] gvfsd-trash
_ (←cursor)

(much lower on the screen:)

[illegible] ethernet failed (←on the right edge)

***************

I should mention that I’m using SSHFS to keep some parts of my fileserver mounted most of the time. SSHFS tends to interfere with suspend (and the network going up and down), so I have a little script in /etc/network/if-{down|up}.d that mounts and unmounts everything when the network status changes. I mention this because I noticed that the trash view is a bit slow whenever the SSHFS mounts are on (presumably because it has to search for trash there, too). Since the mountpoints go away when the network is turned off right before suspend, gvfsd-trash might be doing something that just takes too long. Perhaps retries work because the remote filesystems don’t have time to get mounted yet, or something similar.

I’ve been looking for suspend logs and system messages but couldn’t find anything. Also, I tried the mainline kernel a while ago (because of another issue), and it didn’t seem to affect this. Maybe someone has ideas for further debugging?
