The kernel currently in karmic-proposed stops the driver crashing on the
scan events. However the event still regularly kills the upper layer
throughput with the wireless layer still thinking it is connected
properly.
Doing a remove of the module at that point gets you
Nov 14 07:23:35 acer-aspire-5536 kernel: [ 749.610185] wlan0: deauthenticating
by local choice (reason=3)
Nov 14 07:23:35 acer-aspire-5536 kernel: [ 749.773204] ath9k: DMA failed to
stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x40000020
Nov 14 07:23:35 acer-aspire-5536 kernel: [ 750.203835] ath9k 0000:06:00.0: PCI
INT A disabled
Nov 14 07:23:35 acer-aspire-5536 kernel: [ 750.203909] ath9k: Driver unloaded
however the module will reinsert.
So we're better than we were, but with a way to go.
When the event doesn't cause the driver to crash you get a definite
pause in the throughput.
