pm-suspend doesn't finish after suspend, eats 100% of CPU

Description of problem:
I'm running on a T22 Thinkpad. If I suspend (using pm-suspend) and then
recover, I don't get back to X, I just stay on the console that I went to after
the suspend. I can switch back to X using Ctl-Alt-F7. At that point,
pm-suspend still hasn't returned, and is now eating the entire CPU. This is
running with what I believe are the latest kernel and pm-utils:
Steps to Reproduce:
1. Suspend using pm-suspend
2. Press a key to recover from the suspend
3. Switch back to X
Another potentially intersting detail --- after the suspend, the half-moon icon
on the thinkpad is left flashing. This suggests that it's in some weird
A slight refinement. pm-suspend doesn't take over the CPU until you kill it.
It looks initially like this in ps:
root 6264 0.0 0.5 4448 1388 ? S 19:49 0:01 /bin/sh
And after you kill it, it looks like this:
root 6264 0.0 0.5 4448 1388 ? R 19:49 0:04 /bin/sh
And now it eats the entire CPU. It can't be killed even with kill -9.
That sounds like suspend seems to be hanging somehow in the kernel.
Have you tried newer FC5 kernels? Or would you be even able to test the latest
devel kernels and pm-utils from there?
