Hi

i'm running freebsd stable (last build 28th) and am having a few issues 
with 2 pci serial cards. Basically I'm trying to build a serial server. 
However the driver doesn't seem to work correctly.

Sep 28 22:18:56 boxster puc0: <NetMos NM9845 Hex UART> port 
0xce00-0xce07,0xcc00-0xcc07,0xca00-0xca07,0xc800-0xc807,0xc600-0xc607,0xc400-0xc40f 
irq 9 at device 8.0 on pci0
Sep 28 22:18:56 boxster puc1: <NetMos NM9845 Hex UART> port 
0xde00-0xde07,0xdc00-0xdc07,0xda00-0xda07,0xd800-0xd807,0xd600-0xd607,0xd400-0xd40f 
irq 10 at device 11.0 on pci0
Sep 28 22:18:56 boxster puc1: could not get resource


they are both 6 port serial pci cards, and are listed in the puc driver 
as supported. The  pc is quite old so Im not sure if whats causing any 
issues. I have tried the bios with pnpos enables and disabled but it 
makes little difference. I have also tried with one card and the issue 
is the same.

I have also disabled the pcs onboard serial ports and still no go

I have disabled  ACPI with hint.acpi.0.disabled="1" this seems to stop 
the resource error but I dont get any additional cuad devices


$ pciconf -l -v | grep -B 4 UART
puc0 at pci0:8:0:  class=0x070002 card=0x00061000 chip=0x98459710 rev=0x01

    device     = 'Nm9845 Parallel/Serial Port Adapter'
    class      = simple comms
    subclass   = UART

Any help much appreciated
