I had to borrow the SD card from something else so I'd prefer to have
it back than not blow the fuse :)

Yes, I'm using 8/10.
6.4 is the only one from 6.3 to -current where, when written to the SD card,
I had any output.

The above was on the SD card, this is on the USB stick. IIRC I wasn't able to
get any of the miniroot booting directly from USB stick (but now I am out of
sticks and I don't want to trash the install now I've got it working!).
Though it is possible that I didn't test 6.4 on a stick.
After running the installer and installing -current to USB, serial output
is working.

The one where I had the '"Synchronous Abort" handler' error will have
been an older one from the 6.4 miniroot.
If I dd the current snapshot miniroot to an SD card:
- booting directly fails, no serial output
- mounting and copying in a new u-boot, I *do* now get serial output.
Booting a kernel loaded from SD card doesn't work (transcript below) and
"machine exit" doesn't help any more, but I can "b sd1a:/bsd" to boot
from the USB stick.
So it seems it would definitely help to update u-boot on the build machines.
I missed the arm64.html note (I wasn't expecting to see any installation
instructions there, I'm used to that being only in INSTALL.$arch) but as things
stand it seems like it needs an additional note about dd'ing miniroot to USB as
well as SD, and typing 'boot sd1a:/bsd' or some alternative.
