Title:
  168c:0024 Atheros AR5008 on Ubuntu 10.04 with either ath9k or
  ndiswrapper drivers cause excessive CPU wakeup

Bug description:
  I have recently tried to upgrade my netbook (edit: it is a Notus A12)
  with an Atheros AR5008 Wifi card from Ubuntu 8.04 to 10.04. This was
  done by a clean install (not the Ubuntu dist-upgrade procedure).

  Everything worked fine except for the wireless card. When using 8.04 I
  used ndiswrapper with great success. Now, both the ndiswrapper and
  ath9k drivers give me a very strange problem: They wake up CPU
  excessively making the whole system slow and unresponsive. This
  usually happens after I have connected to a network and try to
  transfer any substantial amount of data.

  If you take a look at powertop output you can see that wakeup number
  usually is below approximately 1500 (even with heavy usage of wifi
  with Ubuntu 8.04). However on Lucid I get often numbers ranging from
  5000 to 15000 which is ridiculously high.

  Once the excessive wakeups have begun, no iwconfig power saving
  configuration or even rmmod-ing the driver helps. Installing wireless
  from backports does not alleviate the problem either.

  This is also present on most other major distributions (OpenSUSE,
  Fedora Core) as well as Ubuntu derivatives (Mint etc). The only
  exception is Arch which uses a newer kernel version (which may or may
  not have something to do with the problem).
