[Prism54-users] 2.6.9 unregister_netdevice loop during system shutdown

[frank-prism54 at mattzz.dyndns.org]

Hello,

I have switched recently from a self-build 2.4.26 Kernel to the
kernel-image-2.6.9-1-k7 kernel provided by Debian/testing

eth1 is a  prism54 based PCI Card

0000:00:0a.0 0280: 1260:3890 (rev 01)
        Subsystem: 10b8:2802
        Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop- ParErr- Stepping- SERR- FastB2B-

                Status: D0 PME-Enable- DSel=0 DScale=0 PME-


During shutdown I have now often a never ending stram of messages:

unregister_netdevice: waiting for eth1 to become free. Usage count=1
unregister_netdevice: waiting for eth1 to become free. Usage count=1
unregister_netdevice: waiting for eth1 to become free. Usage count=1
...

The message seems to come from

net/dev.c but the comments there do not say much to me.

Where should I look next?
