sio0: port may not be enabled

[Stefan Lambrev]

Hi list,

I have some problems with one of my servers and need serial to 
investigate more,
unfortunately I have and problems with serial port too.

from dmesg:
sio0: configured irq 4 not in bitmap of probed irqs 0
sio0: port may not be enabled
sio0: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 flags 0x10 on 
acpi0
sio0: type 16550A

I thought it can be a problem because of shared IRQs .. but vmstat -i 
shows this:

% vmstat -i
interrupt                          total       rate
irq4: sio0                             7          0
irq15: ata1                           69          0
irq20: atapci0                      3783         15
irq21: uhci0 uhci*                     2          0
cpu0: timer                       491698       1990
Total                             495559       2006

from /boot/device.hints :
hint.sio.0.at="isa"
hint.sio.0.port="0x3F8"
hint.sio.0.flags="0x10"
hint.sio.0.irq="4"

uname -srm
FreeBSD 6.2-STABLE amd64

I checked my BIOS - both irq 3&4 are reserved for ISA,
and com port 1 is setup to use irq4 port 3F8.

What else can I check?
