i have tried with tun/tap0 device (modprobe tun, tunctl, ifconfig tap0
1.2.3.4 up, modprobe -r tun - but i only saw that message twice when remove
tun module - and the message went away very soon.
i`m curious, but i cannot even reproduce that at the moment.....

pardon, 2.6.25-git17 in vmware
could you test if this happens with other drivers like tun etc too?
Maybe the bug re-appeared (I didn't follow 2.6.26 development ...)

I am not exactly sure which kernel version Roland (?) is/was using but
from what I can tell this bug is fixed since 2.6.24 (at least). Well I
didn't see it with madwifi nor with the tun devices anymore on any of
the 24.X or 25rc's/25 ...
