I've massive parport problems. When I insmod the parport module,
everything is fine until I try to move the mouse (PS/2 mouse).
Afterwards, mouse, keyboard, ethernet, and probably others don't respond
anymore. I.e. I can't move the mouse, can't type in something, can't
ping the machine, but it still accesses the HD, paints on the screen
(clock, status meter), and even finishs printing. It's not necessary to
print anything, just insmod and mouse movement alone does the trick.
I suspected an interrupt conflict, but there's none, parport0 (part of
the superI/O of VIA's southbridge) is IRQ 7/DMA 3 (ECP 1.9), parport1
(dated ISA slot board, Winbond chip) is IRQ 5 (no DMA, SPP), assigned as
"Legacy ISA" in the BIOS, and the PS/2 mouse certainly is IRQ 12.
Should I use just polling IO, no DMA? Turn of IEEE status readback? Any
other suggestions?
