Could this bug be the cause for the "Trasmitter busy"? I haven't applied
the patch yet but experience with the 2.2.18 driver is that the 
Transmitter busy occurs more frequently than with the previous
version. In my day by day usage, the old driver barfed with transmitter
busy about once in 3 months and the new driver did it already 3 times in
the few days I have it. Still, no doubt, the new driver is much better
since the machine never hangs in the kernel modules. I can always do a
safe reboot in order to try to recover from the problem and BTW, my
Windows buddies are not doing any better anyhow because they power off
their system anyway at the end of their business day.
