Yep, something went in between 21 Oct and now that broke it. I tried a 02 Nov
snapshot as well as a kernel made from -current which includes your recent
uvm revert, both failed:

OpenBSD/i386 (test-i386.vm-7520.int.azathoth.net) (tty00)

Welcome to OpenBSD: The proactively secure Unix-like operating system.

Please use the sendbug(1) utility to report bugs in the system.
Before reporting a bug, please try to reproduce it with the latest
version of the code.  With bug reports, please try to ensure that
enough information to reproduce the problem is enclosed, and if a
known fix for it exists, include that as well.

You have mail.

i386 pmap hasn't been changed in ages, so this likely came from elsewhere. I
made a quick trip through source-changes but couldn't find any likely suspects.
