Andy, Thanks for putting this together. I've given it a go and the results are not as good as others, although better than the vanilla kernel.
On my system I lose the sound initially on boot, and in particular the inbuilt SPDIF is non-functional to start with despite selecting Digital output on the sound preferences. Instead I get a series of clicks from the machine and a bunch of messages in dmesg [ 68.200275] hda-intel: spurious response 0x0:0x0, last cmd=0x670503 [ 68.200277] hda-intel: spurious response 0x0:0x0, last cmd=0x670503 [ 68.200280] hda-intel: spurious response 0x0:0x0, last cmd=0x870503 [ 68.200282] hda-intel: spurious response 0x0:0x0, last cmd=0x870503 This is a regression. On the wireless side the driver is somewhat more stable than orginal. Unfortunately the rate selection algorithm leaves a little to be desired as it is selecting and sticking with rates that are not sustainable. I regularly lose IP throughput to the router despite the wireless showing as connected. When it stick like this and I force a reattachment I get the DMA stall message in the kernel log.
