I was updating the CeroWrtScripts page on the Bufferbloat.net site (http://www.bufferbloat.net/projects/cerowrt/wiki/CeroWrtScripts) and for grins, I ran the cerostats.sh script on my router to see what it had to say for itself.

I'm running CeroWrt 3.10.40-5 (not the latest 3.10.40-6) on my WNDR3800, and dmesg gave a bunch of message like this: 

[735453.398437] ath: phy0: Failed to stop TX DMA, queues=0x004!

I've pasted the full output file into: http://pastebin.com/DYkL0UgB

Uptime says that the router has been up for 9 days 8 hours, so 9.3 days is about 803,000 seconds, so the rash of "Failed to stop TX DMA" ended a day or so ago. The interval between reports seems to be ~5000 to 10000 seconds, so they're not happening too often.

The router's been working fine (at least, I haven't noticed any problem.) Any other info you'd like me to collect?
