Default Bug#648477: linux-headers-3.0.0-1-amd64: ath9k wireless: frequent connection drops (TKIP MIC failure)

Package: linux-headers-3.0.0-1-amd64
Version: 3.0.0-3
Severity: important
Tags: upstream

I observe frequent (1 per minute) connection drops with a new SONY VAIO
notebook. dmesg outputs

[ 200.502509] wlan0: deauthenticated from 00:1c:28:0d:59:2a (Reason: 14)
[ 200.513840] wlan0: deauthenticating from 00:1c:28:0d:59:2a by local choice
(reason=14)

The problem seems to be correlated with high bandwidth traffic (>1 MB/s).
Thechipset is

02:00.0 Network controller [0280]: Atheros Communications Inc. AR9485 Wireless
Network Adapter [168c:0032] (rev 01)

Disabling hwcrypt as suggested in http://www.mail-archive.com/ath9k-
devel@lists.ath9k.org/msg04221.html seems to fix the problem (it didn't re-
occur now for some days since I changed the configuration).
