When I first wrote

I omitted a key point: I normally install GENERIC-NODEBUG.
I wondered whether GENERIC would be less prone to the problem. For
around two weeks I ran GENERIC e140d551b78 without a problem.
For the next upgrade, I chose GENERIC-NODEBUG 01235012e5b. Problems
recurred immediately; a series of six or seven boot failures.
IIRC the first successful boot was with a combination of single user +
verbose mode.
Since then: a mixture of failures and successes, with an ongoing sense
that single user + verbose mode is likely to work around the problem.
This morning I changed loader.conf
from boot_verbose="NO"
to boot_verbose="YES"
– I'll reboot frequently over the next few days, to get an idea of
whether verbosity reduces the likelihood of the problem. Gut feeling: it
will make little or no difference (I'm almost certain that I tried
verbose boot alone, at the boot loader menu, a few times in the past,
without success).
