Quite likely this is it. Thank you.

On Friday I created an i386 VM to test Bullseye installations. The
first such event shows up in syslog at about the same time. The first
event shows up in syslog shortly after I created it.

I ran memtest86+ for about 5 hours just now, and it showed no errors. I
have since rebooted the machine into Linux. I have not started that VM
up again, and will leave it alone for a day to see if I get any such
events.

I have a number of amd64 VMs, and I do not recall seeing this error
before. If I can run those without this error, that will narrow things
down to the i386 VM, and that may be worth a bug report.
