I managed to revise my bisect script sufficiently enough to get reliable
results. It looks like the culprit is commit 503e554782c9 (" debugobject:
Ensure pool refill (again)"); see bisect log below. Bisect on four
different systems all have the same result. After reverting this patch,
I do not see the problem anymore (again, confirmed on four different
systems). If anyone has an idea how to debug this, please let me know.
I'll be happy to give it a try.

Thanks,
Guenter
