This isn't a regression.
I was seeing these problems on 2.6.21 (but 22 was in -rc so I waited
to try it).
I tried 2.6.22-rc4 (with Tejun's patches) to see if it had improved -
no.
Note this is a different (desktop) machine to that involved my recent
bugs.
The machine will work for days (continually powered up) without a
problem and then exhibits a filesystem failure within minutes of a
resume.

OK, that gave me an idea.
Freeze the filesystem
md5sum the lvm
hibernate
resume
md5sum the lvm
<snip>
So the lvm and below looks OK...
I'll see how it behaves now the filesystem has been frozen/thawed over
the hibernate...
And it appears to behave well. (A few hours compile/clean cycling kernel builds
on that filesystem were OK).
Historically I've done:
sync
echo platform > /sys/power/disk
echo disk > /sys/power/state
# resume
and had filesystem corruption (only on this machine, my other hibernating xfs
machines don't have this problem)
So doing:
xfs_freeze -f /scratch
sync
echo platform > /sys/power/disk
echo disk > /sys/power/state
# resume
xfs_freeze -u /scratch
Works (for now - more usage testing tonight)
