Description of Problem: After reinstalling a RH 5.2 system with RH 7.2 (with all current updates included), the PS/2 mouse is not usable anymore. Kudzu says the mouse is missing. When starting gpm and/or when starting X, the keyboard is locked and the mouse can't be used either. After killing gpm and/or X, the keyboard can be used again. However, Anaconda could use the mouse. So, afterwards I installed the kernel-BOOT package and booted this, and indeed, then gpm and X works fine and Kudzu finds the mouse again! Version-Release number of selected component (if applicable): Both 2.4.7-10 and 2.4.9-31 have the same problem: the BOOT kernel works, normal kernel does not work. Configuration: Intel MS440GX (Xeon) mainboard with PS/2 keyboard and mouse. Other info on request.
440GX chipset Intel boards all have a stupid bios bug (bad $PIRQ table). You need to use the smp kernel to avoid this bug.
Checked, and using the SMP kernel works, so this is a viable workaround this problem.
