Odd-looking serial console prompt on RPI2

Recently the serial console prompt on an RPI2 running
FreeBSD 12.0-CURRENT #15 r314322
has become corrupted. The initial output from U-boot and
the early part of the boot phase looks normal, but here it goes off:
Release APs

random: unblocking device.

Feeding entropy:.
There are a few dropped characters in the output from fsck, for example.
Finally, the login prompt looks like this:
n: eBSD/arm (www.zefottyu0)
Any attempt to type causes the line above to repeat without echo of the
typed characters at each keystroke.
If anybody has a hint what's wrong I'd be grateful. One thing I haven't
done is reboot the host driving the FTDI usb-serial adapter. It's been
perfectly stable for more than a month running r311959, so it seems an
unlikely culprit.
Thanks for reading,
