Resolution: fixed
Status: newclosed

The crash should be fixed in hrev43320. It means that the UHCI constructor failed, probably when trying to reset the controller, so there may still be an underlaying problem. It's possible that the UHCI controller is advertised as present, but simply doesn't do anything, as the report you attached would suggest (it only mentions EHCI busses). If you could get a syslog from a successful boot that'd be great. I'll close this ticket as the problem here is now fixed, depending on the syslog a new ticket may need to be created.
