[linux-pm] intermittent suspend problem

Right now I'm running v2.6.31-rc4-169-g967e4bf and it produced
something I've never seen before (neither on 2.6.30 nor 2.6.31-rc3).
The hibernation process froze like this:

Looking for splash system... Splashy ERROR: Cannot read XML File <</etc/splashy/config.xml>> Exiting...
Splashy ERROR: libsplashy: No config file found at (null)
splashy_init: error -1none
s2disk: Snapshotting system
s2disk: System snapshot ready. Preparing to write
s2disk: Image size: 240872 kilobytes
s2disk: Free swap: 1333596 kilobytes
s2disk: Saving 60217 image data pages (press backspace to abort) ... 100% done (60217 pages)
s2disk: Compression ratio -63208.85

Basically, it looked like it simply neglected to switch off the
machine (ThinkPad R50e), switching it off and later on manually
resulted in a perfect resume from the written image.  However, the
next suspend to RAM failed with this:

[66105.285713] Freezing user space processes ... (elapsed 0.02 seconds) done.
[66105.313558] Freezing remaining freezable tasks ... (elapsed 0.00 seconds) done.

where the machine froze with its suspend led blinking.  After a clean
restart, I couldn't reproduce either problem.  Sorry for being of so
little use, but I decided to report it, who knows...
