I have bought a "Super-speed Express Card To USB 3.0 1-Port" to connect an USB3 hard disk to my Thinkpad T510, which only has USB2. Trying to hot plug the express card did nothing, but I guess that is expected. Hence, I booted with the express card already inserted, only to receive a panic upon xhci0 initialization, see below. This is on FreeBSD 9.0-RC1/amd64 with a generic kernel installed from the official DVD. I guess I could test 226803 mentioned in http://lists.freebsd.org/pipermail/freebsd-usb/2011-October/010746.html , which happened after RC1, but from the commit message, it only fixes suspend and resume. As I do not have much time now, should I test 226803, find a Linux CD to actually identify the device, or anything else?
