hfc isdn cards & zaphfc in domU

["Czakó Krisztián" <slapic@linux.co.hu>]

Hello,

After searching the archives, I've found only two messages regarding
this case, but there were no solution.

I have a similar problem, so I try to ask here.

I have twi HFC chipset ISDN cards in my pc:
0000:00:0d.0 Network controller: Cologne Chip Designs GmbH ISDN network controller [HFC-PCI] (rev 02)
        Subsystem: Cologne Chip Designs GmbH ISDN Board
        Flags: bus master, medium devsel, latency 16, IRQ 11
        I/O ports at b800 [disabled] [size=8]
        Memory at de800000 (32-bit, non-prefetchable) [size=256]
        Capabilities: [40] Power Management version 1

0000:00:0e.0 Network controller: Cologne Chip Designs GmbH ISDN network controller [HFC-PCI] (rev 02)
        Subsystem: Cologne Chip Designs GmbH ISDN Board
        Flags: bus master, medium devsel, latency 16, IRQ 3
        I/O ports at b400 [disabled] [size=8]
        Memory at de000000 (32-bit, non-prefetchable) [size=256]
        Capabilities: [40] Power Management version 1

Note that "I/O ports at b400 [disabled]". Why is it disabled?

I've downloaded the bristuff driver, and compiled it with "make
ARCH=xen". The driver installs correctly, finds the cards, but when I
issue the ztcfg command, the domain crashes immidiatly:

************ REMOTE CONSOLE EXITED *****************

The kernel is a 2.6.11.7 with the patches from 2.0-testing xen source. Xen itself is 2.0.5 stable. Can it cause the problem?
The kernel is configured as a privileged guest, based on the dom0 config.

Here's the config of this vm:

kernel = "/boot/xen/xen-linux-2.6.11-xenu-priv"
memory = 256
name = "testvm"
nics = 1
ip = "192.168.1.10"
gateway = "192.168.1.254"
hostname = "testvm"
disk = [ 'phy:vg00/testvm,sda1,w', 'phy:vg00/testvmpv,sdb1,w' ]
root = "/dev/sda1"
restart = "onreboot"
pci = [ '0,0d,0', '0,0e,0', '0,0f,0' ]
