SubjectPressing numlock locks up PS/2 mouse and keyboard
Hi,
I just finished with compiling a Linux system from source 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/or X 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 or X and start it
again (PS/2 protocol), 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 (e.g. +
signs) on screen. This affects X without GPM and X with GPM in repeater
mode, too.
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 gpm
and X mailing list archives, and although there seemed to be similar
problems in the past, I found no fix for my problem. I also asked on the
gpm mailing list and on comp.os.linux.hardware, but so far no one can
help me...
When I boot from a KNOPPIX cd (AFAIK only difference to my system: gcc)
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...
I also tried booting 2.4.13, but it won't boot, oopsing because of a
null pointer reference and trying to kill init...

Any suggestions?
Thank you,
Chris
