>Synopsis: crash on booting GENERIC.MP since upgrade to Jan 18 snapshot
>Category: kernel amd64
>Environment:
System : OpenBSD 7.0
Details : OpenBSD 7.0-current (GENERIC) #265: Wed Jan 19 11:41:29
MST 2022
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
Since I upgraded to from a Jan 5 snapshot to Jan 18, I am
unable to boot GENERIC.MP anymore. I am still able to boot
bsd.rd and bsd.sp - I am sending this bug report from this
computer running bsd.sp.
When I boot the MP kernel, it fails after the lines:
wsdisplay0: screen 1-5 added (std, vt100 emulation)
iwm0: hw rev 0x200, rw ver 36.ca7b901d.0, address a4:34:d9:9f:c7:e3
Most of the time, the screen just goes black, some of the time
it ends up in ddb with the messages below. When the screen goes
black, sshd doesn't seem to start as I am unable to find the
machine with arp-scan or ssh into it. It still happened after
I updated to snapshot from January 19. Judging from the
persistence and the different ddb output, I don't think this is
the same issue as in Ralf Horstmann's bug report
(https://marc.info/?l=openbsd-bugs&m=164254620414598&q=mbox)
Here the (handtyped) ddb messages from the crash:

Of note, this machine an Intel Xeon W-11955M which is a bit off
the beaten path. It exhibits other unexpectedly buggy behavior
since I bought it, but that hasn't been disruptive like this.
Such other bugs including smtpd daemon failing since circa
November, and sometimes kernel relinking after sysupgrade never
completing. Those are beyond the scope of this bug report, but
I'm mentioning in case this pattern of failure may be
recognized by someone more knowledgeable than me. Otherwise, I
am intending to address them at a later point.
>How-To-Repeat:
boot recent GENERIC.MP kernel on this machine.
>Fix:
booting SP kernel seems to work around the problem.
