Sounds exactly like the same problem I was having. I posted about it recently on this list. Downgrading to the latest 2.6.34 made everything work normally again. > Is there a proper venu for debugging such matters, or should I just wait for > this kernel to go prime-time? Well, 2.6.35 is already prime-time as far as it has been released and is not RC... The proper way to debug would be to do a git bisect of the kernel.org sources until you find the exact patch that broke things. I haven't had time to attempt such a feat yet, so I'm just waiting patiently for someone else to figure it out instead. :)
