Dear Warner, Dear John,
I believe the problem is solved now. Although the live debugging
did not turn up anything useful to me, meanwhile, I stumbled
upon something else:
In a newsarticle
was mentioned, together with a (different) problem on a
Thinkpad (different model). I set this sysctl to 1
in /boot/loader.conf and now, it appears the system works
like charm now.
I'm not sure how to rate this. I guess it means quirky
hardware, that is out of spec, but there exists a workaround.
I'm happy that my system seems to work now, but I guess
the panics should be prevented. Maybe the quirky hardware
can be detected, a big warning messages issued during boot, and
the workaround activated? Well, I guess that would be difficult
if not impossible, otherwise it would have been done already.
Please submit this workaround to the PR (my last email to you
and freebsd-gnats-submit@ was somehow not included into the
audit trail). Feel free to close it then.
Thanks again for your explanations.
