Good question. And I think you will find my new finding even more
confusing: With your two patches from this e-mail, I could
suspend+resume 3× with no problems.. With just your two debugging
patches applied.
Lovely heisenbug here. I'll add that for every test so far I've removed
the kernel source tree, re-untarred it and applied the patches from your
e-mails on that, so the tests should be consistent. As is the bug
normally, before we started testing patches the crashes were already
always *very* reliably happening exactly after the third resume.
Just to be sure this morning was not a fluke, I've retested your patch
from this morning, and still a crash on the second resume.
