SubjectRe: 2.0.1: Serial mice problems
   Date: 	Fri, 5 Jul 1996 01:57:01 +0300 (EET DST)
From: Cristian Gafton <gafton@sorosis.ro>

After installing 2.0.1 gpm will stop working in the following scenario:
- start gpm, everything is okay as long as I switch between text consoles;
- startx, then ctrl+alt+Fx, back to a text console. Now gpm is in the
nowhere land. I have to restart it. With 2.0.0 everything is okay.

Some serial driver issues ?

Back out the change that was made between 2.0.0 and 2.0.1 in
drivers/char/serial.c, and let me know if this fixes things.

I suspect this is yet another fallout of the Unifix "POSIX"-fication
patch to the serial driver. (Although as far as I can tell what we're
doing now is just fine as far as POSIX goes; I suspect the folks at
Unifix were trying for System V compatibility in this case.)

Linus has said that he'll back it out for 2.0.2, but if this is really
required for X/Open Spec 1170 branding, we might have to do a lot of
careful planning to keep gettys, gpm, etc. from breaking.
