[Cerowrt-devel] 3.10.40-5

Tue May 20 03:23:15 EDT 2014

Hi Dave,

so I took 3.10.40-5 through a bit more testing and it looks quite good. For example, running netperf-wrapper's RRUL test agains t the router used to produce plenty of the " ath: phy0: Failed to stop TX DMA, queues=0x00e!" errors, but with 3.10.40-5 there is not a single of these errors in the logs, neither for testing the 5GHz radio nor for the 2.4GHz radio. So either the error message got silenced ;) or, preferably, the root cause was fixed.

I fear this might be the logging… at least for ph0 the MAC hangs used to correlate with the TX errors in dmesg...

Neither radio got stuck (but I never could reproduce the locking reliably anyway, so that does not mean much...)

On a related note I get the following two Oopses? from netserver:
