>Description:
The Atheros WLAN driver in NetBSD seems to have some issues with the AR2413 chipset.

I get a lot of these:
ath0: device timeout (txq 1, txintrperiod 5)
ath0: device timeout (txq 1, txintrperiod 4)
ath0: device timeout (txq 1, txintrperiod 3)
ath0: device timeout (txq 1, txintrperiod 2)
ath0: device timeout (txq 8, txintrperiod 1)
ath0: device timeout (txq 8, txintrperiod 1)

Sometimes, when I reconfigure the device several times in a row, the system will even freeze up and needs to be powercycled.

This is being observed on a PC Engines alix2d3 with a Compex WLM54G miniPCI card.

The card works fine on Linux and pfSense. The OpenBSD driver works in general, but has similar issues and does not support 802.11g on this chipset.
