I have an external USB3 hard drive that use for backup purposes. *This morning everything worked fine, until suddenly the computer froze completely and was non-responsive to local or remote commands. * After I hit the reset button and it come back up, the HD no longer connects via xhci (though it works fine via ehci). *I recompiled my kernel with xhci debug messages, but I really don't have a clue what this stuff is talking about.


I've attached the output of dmesg | grep -i xhci. *If anyone can make more sense of this than I can, I'd surely appreciate it.
Thanks!

I guess no one here knows the answer. There is a linux.usb.general
mailing list on gmane that seems like a promising place to ask, though.

Maybe try the usb-storage mailing list:
https://lists.one-eyed-alien.net/mailman/listinfo/usb-storage

I have USB3 ports but no USB3 devices, so no experience with its
potential problems yet...
