Hi,
Not sure if this is the commit or not, but a kernel from the 18th seems to function normally, and a kernel from today has a great deal of messages like the ones below. I also dont know if this is just exposing an existing bug in the driver that was upto now hidden ?
Boot time, I see the following

Looking at the pciconf output from the older kernel, the unsupported request is there too
