I've noticed during several Sparc autoupdates that after X dies, the console
remains completely blank throughout almost the entire update, up until the
point where the machine is about to reboot (you can see the last few daemon
death messages).
tlyu saw byte-me doing this today and he came up with a possible reason,
namely that the console application might not be getting killed and might
still have a hold of the real console device. Then when the machine shuts
down and kills everything, after it hits console, it would make sense for the
last few messages before reboot to appear.
This caused me to do a bunch of debugging, and the above idea didn't pan out.
Remotely 'kill -FPE'ing dm results in getting a blank screen and neither
console nor xlogin nor Xsun are running. However, echoing things to
/dev/console doesn't cause them to show up on the screen. I've looked through
dm, and think I may have an idea why this happens. I'm submitting a patch
that seems to fix the problem.
