Thanks. It would be good to repro with a Free Software test driver.
Certainly good to ask if others are seeing issues. If you see the problem with 10.1 and 11.0_RC2, I see almost zero point in testing netbsd-10 tip. I use cgd on gpt on umass-dock-sata, but not a lot of simultaneous accesses. I have not had problems. I know that doesn't prove much...
