[gpm]Mouse and then keyboard locking up

[Chris Schwemmer]

I just finished with a complete install of a Linux from Scratch system 
using gcc 3.2, glibc 2.5, kernel 2.4.19, binutils 2.13 and bash 2.05a 
running on an Athlon TB 1000 MHz, Asus A7V mainboard (VIA KT133 
chipset), 384 MByte RAM. Now I noticed that when I use GPM and I press 
Numlock, then the mouse (PS/2 made by Logitech, 3 buttons, 3rd button is 
a wheel) stops working (the cursor disappears). When I kill GPM and 
start it again (-m /dev/psaux -t ps2), the keyboard stops working too. 
The log shows kernel messages saying 'unrecognized scancode (70), 
ignoring' or sometimes 'timeout - no AT keyboard connected?'. When I use 
the imps2 protocol, keyboard and mouse stop working as soon as I start 
GPM for the first time, but now the keyboard produces wierd characters 
on screen. This also happens in X when GPM is not running and in X when 
GPM is in repeater mode.
I already tried kernel 2.4.18, disabling APM, changing device 
permissions, using other PS/2 mice and using another gpm binary from a 
system where it works. I checked the archives of this list and the 
kernel mailing list archives, and although there seemed to be similar 
problems in the past, I found no fix for my problem.
When I boot from a KNOPPIX cd everything works, I can use both GPM and X 
without any problems. The Linux I had before on this PC worked ok, too, 
so the hardware is alright...
Any suggestions? I need this system asap for work... this ain't funny 
anymore...
