Title:
  "ath: phy0: failed to stop TX DMA" lines pop up randomly, shutting and
  opening lid goes back to working system

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I get this issue randomly when using my system (13.04 64bits on Asus
  F201E, up to date with proposed repos). It started about a week ago
  (not sure exactly though).

  The system randomly shows a screen with lines more or less saying the
  following:

  ath: phy0: failed to stop TX DMA, queues=0x00... !
  ath: phy0: DMA failed to stop in 10 ms AR_CR=... AR_DIAG_SW=... DMABG_7=...
  ath: phy0:  Could not stop RX, we could be confusing the DMA engine when we start RX up.

  The ellipses point out variable values or strings I could not be
  bothered to write down.

  To get back to a working system, I just have to close the lid of my
  laptop and open it again. I can then use it normally, until it happens
  again.
