OK, did two full rebuilds,once using ssh, once using x. The one using ssh
was fine, the one using X did hang the console, but the only way to notice
that was because the PC speaker hangs while sounding off.
I read the commitlogs, the only one that seemed at all connected with the
console was this one (a weak link, admittedly):
============begin commit message====================================

Modified files:
sys/kern subr_bus.c
Log:
devd kernel improvements:
1) Record all device events when devctl is enabled, rather than just when
devd has devctl open. This is necessary to prevent races between when
a device arrives, and when devd starts.
2) Add hw.bus.devctl_disable to disable devctl, this can also be set as a
tunable.
3) Fix async support. Reset nonblocking and async_td in open. remove
async flags.
4) Free all memory when devctl is disabled.
