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 (probe1:twa0:0:1:0): INQUIRY.
