ath5k_pci: gain calibration timeout / unable to reset hardware -11

Hi,

I was using the ath5k_pci driver on a macbook pro 1,1 and it is working for some time but then suddenly messages like the ones below appear and I have to *turn off* the machine to get it back working (even booting to osx is not sufficient - osx won't have network when things go wrong as they do after a couple of hours). Note that this happens with both 2.6.27 and .28.

Hi Soeren,

Thanks for the report. It is a known problem, with a bugzilla entry already:

Hi,

I was using the ath5k_pci driver on a macbook pro 1,1 and it is working for some time but then suddenly messages like the ones below appear and I have to *turn off* the machine to get it back working (even booting to osx is not sufficient - osx won't have network when things go wrong as they do after a couple of hours). Note that this happens with both 2.6.27 and .28.

Does the _HW lockup_ happen even with 2.6.28? The lockup should be gone there (with the messages still present).

I see Bob already replied, ignore me, he knows better.

I thought Felix's patch had gone into .28, but in fact it hasn't. We should probably get it in or queue it for .28.1 -- it's a two liner that will fix a lot of people's setups.

John, if you're reading, that's 23c401574b16cb2b6d2231ba405ebf85b8c87de5 in wireless-testing.

The lockup can still occur, but it's a lot less frequent with his patch.
