Backfire (10.03.1-RC5, r26741) on WRT160NL

I am using backfire from SVN and the following messages are diplayed multiple times in the log when wireless stops working.

Jan  1 00:12:34 AR1 user.err kernel: ath: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x42000020 DMADBG_7=0x00006020
Jan  1 00:12:34 AR1 user.err kernel: ath: Could not stop RX, we could be confusing the DMA engine when we start RX up

I am continiously sending a 128kbit stream from the wireless side for measurement purposes of a University project.
A wireless node connects - disconnects - connects ... every 20 seconds

The WRT160NL is in routing mode (not bridged), which maybe causes a little more CPU load then in bridged mode.
