The driver is the zd1211-r77 (the last of the older zd1211 drivers
before the "zd1211rw" project. I need Ad-Hoc which isn't supported in
the rw project.
I've also narrowed the issue down a bit. The first failure is a
transmit timeout (it looks like 10 seconds) which causes a reset of
the interface. Unfortunately, the URB is never given up in the
timeout which explains the alloc failure of the next urb which
follows, and that is not recoverable.
The code which detects the timeout has a comment about kernels 2.6 and
higher not handling free urb in an interrupt context, so it is
deferred, perhaps I'll try freeing the urb there since I am using 2.4,
but I still don't think that will fix my problem which is the timeout.
