Hi,
Somewhere along the line the code in FreeBSD that maps irq 2 to irq 9 has
gone away and a panic was added if one tries to use irq 2. This is all
well and fine, except that the pnp code was not notified of this. :-) So
if you have a pnp device that have irq 2 in its mask and FreeBSD then
decides that irq 2 is a good irq to use for this device, you have an
instant panic.
I have worked around it with this crude patch below. Crude because:
1) I don't know if it should be an i386 only fix, and
2) I used 0x04 directly, maybe IRQ_SLAVE from i386/isa/icu.h or
some other difine should be used?
