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).
