[rin <rin%NetBSD.org@localhost>]

details:   https://anonhg.NetBSD.org/src/rev/718aabb7a898
branches:  trunk
changeset: 960005:718aabb7a898
user:      rin <rin%NetBSD.org@localhost>
date:      Fri Mar 05 06:14:47 2021 +0000

description:
pckbcintr() must be running with IPL_TTY, not IPL_SERIAL. Otherwise,
tty(4) routines are unexpectedly interrupted, which results in
"locking against myself" errors for tty_lock.
