Thanks. There have been some AR9485 fixes upstream recently. Could
you test v3.1 from experimental?
If that fails, please report it upstream to
ath9k-devel@lists.ath9k.org, cc-ing linux-wireless@vger.kernel.org and
either me or this bug log so we can track it.

Hi Jonathan,
linux-image-3.1.0-1-amd64 indeed seems to fix the problem. I tested for
half an hour now without any connection drop issues. Thanks and sorry
for bothering you...
Best Regards
Christoph

Thanks. I should have remembered; sorry to waste your time.
(So I don't forget: commits squeeze is missing include
- v2.6.38-rc1~476^2~169^2^2~53 (ath9k_hw: Define hw version macros
for AR9485, 2010-12-06) .. v2.6.38-rc1~476^2~169^2^2~28 (ath9k: Add
device id of AR9485 to pci table, 2010-12-06)
- [v2.6.38-rc1~476^2~169^2^2~22 (ath9k_htc: Fix panic on FW download
failure, 2010-12-07) doesn't seem to be related but should probably
also go in the stable tree]
- v2.6.38-rc1~476^2~14^2~3^2~62 (ath9k_hw: Fix bug in eeprom data
length validation for AR9485, 2010-12-21)
- v2.6.39-rc1~468^2~417^2~42 (ath9k: Fix a PLL hang issue observed
with AR9485, 2011-01-27) .. v2.6.39-rc1~468^2~417^2~39 (ath9k_hw:
Update PMU setting to improve ripple issue for AR9485, 2011-01-27)
- v2.6.39-rc1~468^2~25^2^2~170 (ath9k_hw: Updates for AR9485 1.1
chipsets, 2011-02-18) [wow, is the commit message unhelpful]
and some other commits from the same merge
... and so on. Grepping for AR9485 and for ath9k_hw should hopefully
find everything.)

No need. Christoph tried v3.1 and found that it was fixed.
Thanks for looking it over,
