I imagine that these are the "9 commits" you mean: > git rev-list c30ae13..4cebb34 4cebb34caa5122216a1e2451eae9e0fc47ec2589 a0b907ee2a71052fefdf6151764095f3f97b3275 c31b5c9c806b1fbdc9e98885d897664a0d482989 e7aecd327d80b2f156b54769013aaccb2a20645a 8efa5d7d6ad307ae2d220def37ca89594062c40d 4aa5d783c9e1c72e4950ff34f388077ccecac74a e5b046d86fac609f636d127a38de94a175c7e83b 132b1c3ee38ea6fa0501004fd0f19acb554e5a44 aeae4ac9090462ea38387dcdbac4f01b944af6a4 Most of those look fairly harmless so long as you don't define CONFIG_ATHEROS_AR231X. Just to narrow things down...if you only revert the first 8 (i.e. leave aeae4ac alone), do you still have problems? Or does it still "stabilize"? That patch converts the driver to the generic DMA API. It seems OK at first glance, but I suspect it is the only one likely to be effecting your situation. John -- John W.
