I like zzz(8) because the name is so short and convenient. Given that
apm is mostly deprecated, wouldn't it be possible to switch zzz over to
write that sysctl value instead?

Alright, I tried disabling whatever I could think of, in various
combinations. So far, it didn't help. I see a message about
"Syncing disks" and a number.
I tried disabling audio, video, bluetooth, sdhc/sdmmc, usb etc., but
nothing so far helped. Why do I need remote debugging capabilities and
how do I do that? Via a serial line? Maybe the machine has a serial
connector on the inside...
Any other ideas? If you were me, and looking at this dmesg, what would
you disable first? Are any of the drivers in the dmesg known to be
substandard quality or known to cause breakage, or have they recently
(i.e. between 5.1 and 5.99.5x) undergone changes?
I might be overlooking things.
