Note: I told Joe to mail freebsd-usb@ about this, since it looks like it pertains to the USB stack, and Hans tends to respond to stuff there. That said... Looking at commits between r250508 and r250707, my gut says it's very likely one of these (with the most probable being marked with arrows): http://www.freshbsd.org/commit/freebsd/r250581 http://www.freshbsd.org/commit/freebsd/r250561 <--- http://www.freshbsd.org/commit/freebsd/r250560 <--- http://www.freshbsd.org/commit/freebsd/r250559 How I got that list was by manually reviewing the following: http://www.freshbsd.org/?branch=RELENG_9&project=freebsd So I would recommend rolling back to r250558 (the last stable/9 commit to happen before r250559) and see if things improve. Again, my gut feeling says that they will, and that r250561 or r250560 are responsible. -- | Jeremy Chadwick jdc@koitsu.org | | UNIX Systems Administrator http://jdc.koitsu.org/ | | Mountain View, CA, US | | Making life hard for others since 1977.
