Excellent call, removing mouse, keyboard and pl2303TA adapter
eliminate the timeout messages and make the console much
easier to use. Only the USB flash drive holding /usr, /var,
/tmp and swap remains.

It looks as if u-boot and loader are both behaving reasonably;
they respond to commands, with no extraneous output. 

A hands-off boot still fails silently with the red LED stuck on,
for both /boot/kernel and /boot/kernel.spare.

/boot/kernel.old, at r327228, _does_ boot, but with errors, like so:

.....

FreeBSD/arm (www.zefox.com) (ttyu0)

login: UFS /dev/ufs/rootfs (/) cylinder checksum failed: cg 0, cgp: 0x9e441246 != bp: 0xfa67bf3a
UFS /dev/ufs/rootfs (/) cylinder checksum failed: cg 0, cgp: 0x9e441246 != bp: 0xfa67bf3a
handle_workitem_freefile: got error 5 while accessing filesystem

Login on the console worked, repeated fsck -f cycles permitted return
to multi-user without errors.

Sources are now updated to 327548, /boot/kernel.old has been copied over
/boot/kernel.spare and a new cycle of build/install in /usr/src is running.

Thanks _very_ much!
