[Bug 610048] [NEW] suspend doesn’t work most of the time

Mon Jul 26 12:01:21 UTC 2010

Public bug reported:

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?
