It stopped when I rebooted into the old kernel under the name
/netbsd. If it had happened only once I would have written it off,
but the sequence of events was:
1 Put new kernel in place as /netbsd, move old one to /netbsd.old .
2 "shutdown -r now", machine crashes while booting, select "reboot"
from db> prompt, which seems to cause a hard reset (machine goes
through the BIOS's "discover devices" sequence).
3 Boot into /netbsd.old by name.
4 Weirdness occurs, but am able to put old kernel back as /netbsd .
5 "shutdown -r now" (I think it crashed during shutdown, but I'm not
sure I remember this part accurately).
6 Boot into old kernel in normal location; all's well.
7 Try again to build new kernel after removing old object files.
8 Repeat steps 1-6 exactly.
So it happened twice, and both times the weirdness occurred while
I was booted into the old kernel using the name /netbsd.old, and
stopped after I rebooted into the the old kernel using the name
/netbsd. The name may be a red herring; I did not have the patience
to try, say, booting twice in a row into /netbsd.old.
Anyway, this is just to answer your question for completeness; it
is probably unrelated to the "i915 crash". I am about to try
building a new kernel using all the advice I've received over the
past 2 days...
