Re: ath9k DMA problems

Am I the only one having these problems? ath9k hasn't worked well for me since 2.6.29.4; every snapshot since then has suffered from random drops. In 2.6.29.6 it at least would quickly reassociate. The current ones hang within 20-30 minutes of use and never come back. The compat-wireless snapshots have all been equally unusable.

Still seeing occasional hangs using the ath9k in 2.6.31-rc6, and even worse
using compat-wireless 2009-08-22. Today I got this which was even more
interesting:

[369014.776586] wlan0: associate with AP 00:12:17:26:56:10 (try 1)
[369014.779197] wlan0: RX ReassocResp from 00:12:17:26:56:10 (capab=0x411
status=0 aid=2)
[369014.779197] wlan0: associated
[369472.707961] ath9k: DMA failed to stop in 10 ms AR_CR=0xdeadbeef
AR_DIAG_SW=0xdeadbeef

This is on an HP dv5z laptop, it reports an AR9280 at boot.
