Hi all,

I'm experiencing occassional crashes where the system becomes fully
unresponsive.  Nothing is written to ddb (after a few times, I
redirected console output to the serial port and have a machine
listening full time), there is no response on the network, not to the
keyboard (caps lock etc LEDs don't light up when pressed) and there is
no response to a break over the serial console.

The only thing I can relate this to is "heavy-ish" X redrawing when
there is "some" system load; moving a window with a large image
around or going into the Web Developer Tools in Firefox .. but doing
those things to try to trigger the issue has never been succesful
(very vague, I know).  This is on inteldrm0: msi, HASWELL, gen 7

I regularly update to newer snapshots, and because these hangs are so
infrequent, it's hard to pinpoint when this started: I often upgrade
before it happens.  Included below are the dmesgs of the kernel that
hung and the one from today's latest snapshot that I upgraded to
afterwards.  In this case, I went from

OpenBSD 7.0-beta (GENERIC.MP) #195: Mon Aug 23 23:41:21 MDT 2021
to
OpenBSD 7.0-beta (GENERIC.MP) #211: Sun Sep 12 13:09:48 MDT 2021

(I upgraded end of August somewhere), so almost two weeks without a
problem.

Is there anything I can do to get more output from ddb?

Paul
