Here's another one, followed by savecore deadlock.

So far, so good.

On reboot I get:

Starting ddb.
ddb: sysctl: debug.ddb.scripting.scripts: Invalid argument
/etc/rc: WARNING: failed to start ddb

This probably already indicates some problem?

Eventually I get to:

savecore: reboot after panic: wrong page state m 0xe00000027a9adb40
Oct 15 09:05:50 mech-as28 savecore: reboot after panic: wrong page state m 0xe00000027a9adb40
savecore: writing core to /var/crash/vmcore.9

So here I'm confused.

I think I set up textdump as in the man page.
So I think the core should not be written.
Instead I was expecting ddb.txt, config.txt, etc.,
as in textdump(4).

Anyway, savecore eventually deadlocks:
