Suspend to disk fails after Squeeze upgrade

[Richard Lawrence <richard.lawrence@berkeley.edu>]

Hi all,

I upgraded from Lenny to Squeeze this past weekend.  Since then, I
haven't been able to successfully resume after a suspend to disk, which
had been working fine in Lenny (with Linux 2.6.26).  Basically, on boot,
I see a blinking cursor, followed by a completely blank (unresponsive --
no virtual terminals or anything) screen.

I've got this information from dmesg (more output below):

[    2.027753] PM: Starting manual resume from disk
[    2.027760] PM: Resume from partition 8:5
[    2.027763] PM: Checking hibernation image.
[    2.028125] PM: Error -22 checking image file
[    2.028127] PM: Resume from disk failed.

But I'm uncertain where to look for more information (I can't find
anything more informative anywhere in /var/log), or how to go about
determining whether this is a configuration issue I can fix or a bug
that I should file.

Any pointers would be greatly appreciated!

Best,
Richard
