>Description:
With an AVM B1 PCI interface and the kernel configuration containing this:
# ISDN
device "i4bcapi"
device iavc
device isic
device "i4bq921"
device "i4bq931" 
device "i4b"
device "i4btrc" 4
device "i4bctl" 
device "i4brbch" 4
device "i4btel" 4
device "i4bipr" 4

On boot, the card is detected but the iavc driver fails to attach:

iavc0: <AVM B1 PCI> port 0xd800-0xd81f,0xd400-0xd43f irq 11 at device 13.0 on pci0
iavc0: failed: rid 0x10 is ioport, requested 3
iavc0: can't allocate memory region
device_attach: iavc0 attach returned 6

Though this happens, the driver seems to stay attached and shows up in pciconf:

iavc0 at pci0:13:0:        class=0x028000 card=0x00000000 chip=0x07001244 rev=0x00 hdr=0x00
    vendor   = 'AVM AUDIOVISUELLES MKTG & Computer GmbH'
    device   = 'B1 ISDN controller'
    class    = network

Full kernel config can be found at

full dmesg output at
   http://www.thiemo.net/projects/mygiea/dmesg-isdn

(dirty root device seen in that dmesg came from doing "isdndebug" in the state described above - system just hung up)
>How-To-Repeat:
Have ISDN B1 PCI card, try to use it
>Fix:
Unknown to me.
