Hello.
If you're using a 3270 console with linux-390 you may have noticed that
when you give the "reboot" command your system typically goes into a
disabled loop. Here's a patch to cure the problem. It should apply
cleanly on any 2.4.7, 2.4.9, or 2.4.17 kernel tree. Alan, Martin,
whoever is appropriate, I'd be grateful if you could accept this patch
into your forthcoming work.
