SubjectMouse and keyboard problems with 2.6.0-test9
I've been having mouse and keyboard problems with kernels since 
2.6.0-test6 (at least). The machine I'm testign with has a Supermicro
X5DA8 (Intel E7507 chipset) motherboard with two 3Ghz Xeon CPUs and was
install with Red Hat 9 and updates modutils, kinitrd etc.

When doing large amounts of I/O (we're reading > 300MB/s from disk,
processing it and downloading it across AGP) while running XFree86 the
psmouse gets into a state where it loses synchronisation and cannot
recover. The pointer warps to the top right of the desktop and moving
the mouse generates spurious mouse down events. Switching to a virtual
console and back to the X desktop sometimes recovers, but usually not.

I've tried the psmouse_noext option, various rates including 200 (which
seemed to make things better for a while) and the recent psmouse_rate
with the rate to 0 without success. I've also tried a generic Dell
wheelmouse and and one of those optical Microsoft Intellimouse things.

The keyboard problem is that atkbd.c gets into a state where it starts
generating message like the following for each key press:

Unknown key pressed (translated set 2, code 0x0, data 0x0, on
isa0060/serio0)

These flood the console, making the machine difficult to use. This
mostly happens when I switch between XFree86 and virtual consoles, so it
may be due to my generic PS2 keyboard generating spurious release events
(as mentioned previously
<http://www.ussg.iu.edu/hypermail/linux/kernel/0309.1/2185.html>).
Commenting out the warning in atkdb.c makes the console usable again.

Any suggestions on things to try would be greatfully appreciated.

Regards,

Christopher.
