(third try. I just received an email from the list so maybe mine will go=20
through this time)


My DWL-122 hangs quite regularly. Strangely enough this mostly happens=20
when I'm reading my mail with pine+ssh. So it's not like there is a lot=20
of traffic, but maybe it has something to do with small packets. Here is=20
what I get in syslog when it hangs:

Nov 28 11:39:12 oleron kernel: NETDEV WATCHDOG: wlan0: transmit timed out
Nov 28 11:39:12 oleron kernel: wlan0 rx pipe reset complete.
Nov 28 11:39:12 oleron kernel: wlan0 tx pipe reset complete.
Nov 28 11:40:12 oleron kernel: NETDEV WATCHDOG: wlan0: transmit timed out
Nov 28 11:40:17 oleron kernel: NETDEV WATCHDOG: wlan0: transmit timed out
Nov 28 11:40:18 oleron kernel: hfa384x_usbin_callback: Fatal, failed to res=
ubmit rx_urb. error=3D-67
Nov 28 11:40:22 oleron kernel: NETDEV WATCHDOG: wlan0: transmit timed out
Nov 28 11:40:57 oleron last message repeated 7 times

The first round of messages, at 11:39, is when it manages to recover=20
which is something like 9 times out of 10. The messages at 11:40 show=20
what happens when it completely dies. When that happens the keyboard=20
dies too which essentially makes it impossible to do any postmortem=20
analysis. As the DWL-122 is a USB key, I'm not entirely sure if the=20
problem comes from linux-wlan-ng or the USB subsystem.

Is this a known issue?
What can I do to help diagnose/fix it?

Here is some more detail on my configuration:
