Comments in that bug seem to indicate its not really a master of this.
So I reverted the dup.

** This bug is no longer a duplicate of bug 407040
   ath9k - crashes and unable to reinsert module. Hardware won't reset.

** Changed in: linux (Ubuntu Karmic)
   Importance: Undecided => Medium

** Changed in: linux (Ubuntu Karmic)
       Status: New => Fix Committed

** Description changed:

+ SRU justification:
+ Impact: The mentioned change by upstream (in the Karmic release code)
+ caused regressions for the detection of some devices.
+ Fix: "pci: increase alignment to make more space for hidden code" which
+ comes in through resolves the issue and allows affected devices
+ to be detected again.

  Just opening a bug in launchpad to keep this on our radar and also track
  the issue upstream:
  The Atheros ath9k module is not working with [testing]-kernel on an
  Acer Extensa 7630EZ. Downgrading to 2.6.30.x solves this problem
