IRQ 6 is normally used by the floppy controller. You can see where it is
used on your system by looking at the boot output (using dmesg, for exam-
ple). If you get a line like:
fdc0 at isa0 iobase 0x3f0 irq 6 drq 2: floppy controller
then you know your floppy controller is on IRQ 6. Either your system has
something else that's trying to share IRQ 6, or your floppy controller has
some subtle incompatibility with the standard for such things.
If you have a controller which also has a floppy port (for example, a
SCSI controller), make sure that it's disabled - more than one floppy con-
troller can cause definite problems. If that's not the case, but you do
have another controller available, try disabling the motherboard controller
using the BIOS setup and enabling the add-on controller's floppy port. You
will need to move the floppy data cable over as well.
