#17747: ar9341 tl-wr8410 wireless driver bug:ath: phy0: Failed to stop TX DMA,
queues=0x004
--------------------+-----------------------------------
Reporter: weeds | Owner: developers
Type: defect | Status: new
Priority: high | Milestone: Barrier Breaker 14.07
Component: kernel | Version: Barrier Breaker 14.07
Keywords: |
--------------------+-----------------------------------
when run under some network pressure, it will occur below dmesg, which
show "ath: phy0: Failed to stop TX DMA, queues=0x004", could anyone
explain this ? I think something not right at here.
