I have a very simple problem...whenever GPM is running and I move the mouse, both the mouse and keyboard stop working. When gpm is not running, everything is fine (except I can't use the mouse). This is only in console mode, I haven't configured X yet. I am using a Microsoft Intellimouse PS/2(gpm is started with gpm -t imps2), redhat 6.1, my computer is a dell 350 with no upgrades other than a 3dfx video card. Also, I whenever I try to run "XF86Setup" or "setup" the keyboard stops working, although for the latter I can still alt-ctrl-delete and reboot.
I can't duplicate this problem with the gpm from either 6.1 or the forthcoming 6.2 with a Microsoft PS/2 IntelliMouse. gpm was started with -t imps2. We have no other reports of this bug. Please insure that /dev/mouse is a symlink to /dev/psaux. It should be set this way if you are using a PS/2 mouse.
There has been a thread on the Linux-Kernel mailing list recently, in which Linus himself was a very visible participant, on precicely this subject. It's not one that I took much notice of, but from what I did read, there is apparently some sort of race between the PS/2 and USB subsystems on SOME motherboards that cause exactly the symptoms described to occur. If such is the case, then the bug in question is very real, and Linus himself is very actively trying to track it down, but the cause is currently unknown.
