Re: Suspend to disk fails after Squeeze upgrade
Thanks, Camaleón, for these suggestions.

Ok, here's where I'm at:
1) A new user (pmtest) can indeed hibernate and resume from the console
without issue
2) My regular user account (rwl) can hibernate and resume from the
console without issue
3) pmtest can hibernate the system from within Gnome in X, but a kernel
error results on resume -- though the system recovers. Details below.
4) rwl can hibernate the system from within stumpwm in X. I see no
kernel error on resume (though perhaps it's there, but stumpwm doesn't
give me a nice dialog box the way Gnome did). I have now seen at least
one successful resume after hibernating from stumpwm in X, but my
previous failures to resume were always after hibernating from within
stumpwm in X.

There is indeed. I'm afraid I don't see much of use there, though.
Lots of messages indicating that the /hibernate/ was successful. But
nothing indicating what the problem is when resume fails. I have
included segments of the log below from a successful hibernate/resume
cycle. The only difference I can see between successful and
unsuccessful runs is that, in the unsuccessful runs, there is no data
logged for the "resume" part of the cycle -- which I guess suggests that
the problem occurs before pm-utils even gets into the picture, right?
One other piece of potentially relevant data: my machine seems to have
some sort of hardware quirk that requires about a 35 second "warmup"
period between loading GRUB and booting. (Sometimes, this period is
accompanied by a fan noise that eventually shuts off, after which
experience tells me that the system will boot fine.) If I don't wait
the 35 seconds before booting when the machine is cold, a variety of
strange things can happen (sometimes I see kernel panic type messages,
sometimes nothing at all), but waiting the 35 seconds always allows the
machine to boot successfully. The problem only occurs when the machine
has been powered off and sitting for a while (e.g., overnight) -- I
don't need to wait the 35 seconds when rebooting, for example.
I have no idea what this problem is, nor do I have any idea how I might
begin to find out. It's one of those things that I have reached an
agreement with my machine about: as long as it keeps booting, I'm happy
to wait 35 seconds, and not poke around. :)
Best,
Richard
