 I tried to test this on the Compaq Deskpro EN of the original PR,
 using a -current/i386 built from 2020.07.22.15.01.18 sources.
 
 Typing ctrl-alt-esc on the USB keyboard after booting to multi-user
 results in an immediate "i82489_icr_wait: busy" panic as reported in
 PR 52525, whether the "while true; do ifconfig athn0 down; ifconfig
 athn0 up; done" loop is running or not.
 
 This would suggest that the present PR is fixed, but because of 52525,
 it's hard to get a statistically significant sample of control-alt-esc
 behaviors as each test takes a long time to run with the crash and fsck.
