Norman had a good thought, one which I had not thought of since OpenBSD
pre-selected booting from the MP kernel during the install given the CPU I
am running. I booted up the box on the SP kernel, and was able to get
through a few 30 second stress runs, but then ran one set for 90 seconds
and received another panic:
pmap_page_remove: pg=0xd2342ce0: va=8f9d4000, pv_ptp=0xd2956da4
pmap_page_remove: PTP's phys addr: actual=0, recorded=71112000
panic: pmap_page_remove: mapped managed page has invalid pv_ptp field
Stopped at Debugger+0x4: popl %ebp
RUN AT LEAST 'trace' AND 'ps' AND INCLUDE OUTPUT WHEN REPORTING THIS PANIC!
DO NOT EVEN BOTHER REPORTING THIS WITHOUT INCLUDING THAT INFORMATION!

Am I barking up the wrong tree trying to deduce if I really do have a
hardware problem? I am open to accepting diffs and compiling from source if
other developers think there might be a bug to fix here.
Cheers,
