Dear Gary, I've seen this question several times: "Installed FreeBSD on my XYZ-brand PC, and my keyboard (and probably bus mouse, too) is locking up after switching between vtys (or even spontaneous). What's wrong?" Last time Dave Walton asked this, I gave him a kludgy workaround I knew, and now he himself found something that's supposed to be a real solution. A compile-time option ASYNCH for syscons.c isn't documented in LINT (at least in -stable as of Mar 20) and I don't recall it to be mentioned in any documentation.

In case you come across this problem again, I solved it by adding options ASYNCH to my kernel.
