[ath9k-devel] ath9k disconnects (ath: Failed to stop TX DMA!)

[Mieszko Ślusarczyk]

Hi, 

I'm having problems with TP-LINK TL-WN851ND,

after 3-5 minutes of "heavy" load (hostapd offers 130mbit/s, physically I get ~7.1MBytes/s) I get:

`

and so on.

Ive tried compat-wireless 3.1.1-1 and 3.2_rc1-1

lspci
00:14.0 Network controller: Atheros Communications Inc. AR9287 Wireless Network Adapter (rev 01)
lspci -n
Code:
00:14.0 0280: 168c:002d (rev 01)

Can you try a previous kernel + compat wireless version? say something
2.6.30ish?

(Just in case this is a regression.)
