Here are a couple of patches to help narrow down the issue. http://sujith.github.com/patches/wl/0001-ath9k-Add-some-debug-messages.patc h http://sujith.github.com/patches/wl/0002-ath9k-Resync-beacons-after-a-rese t.patch The first one adds some messages, the second sets up beacons properly in case a HW reset happens. Can you try these and post the log ? If you are willing to move to a more recent kernel, then current wireless-testing would be a good choice since it has various driver fixes. There are a few pending ath9k patches which have not been merged yet, you can find it here: http://sujith.github.com/patches/wl/wl-ath9k-May-29-2012.patch
For the record, we swapped the mini PCI card to a different one of the same model and now it seems to work fine. Could you imagine a hardware fault or tolerance issue causing such errors? Best regards, Tvrtko
