[I've looked in the mail archives and couldn't find a solution....]

I'm running 4.3-STABLE from mid-July. When I boot, I get the following
error:

   sio1: configured irq 3 not in bitmap of probed irqs 0

Now according to the BIOS, the second serial port is set for 0x2F8 and
IRQ 3 (and enabled). [This port works under Windows] Nothing else is
using IRQ 3.

If I boot verbose, I get:

   sio0: irq maps: 0x201 0x601 0x201 0x201
   sio0: <3COM PCI FaxModem> port 0xec00-0xec07 irq 10 at device 19.0 on pci0
   sio0: moving to sio2
   sio2: type 16550A
   sio0: irq maps: 0x241 0x251 0x241 0x241
   sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0
   sio0: type 16550A
   sio1: configured irq 3 not in bitmap of probed irqs 0
   sio1: irq maps: 0x241 0x241 0x241 0x241
   sio1: probe failed test(s): 0 1 2 4 6 7 9
   sio1 failed to probe at port 0x2f8-0x2ff irq 3 on isa0

What am I doing wrong and how do I get this port recognized?

Thanks,
