https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D246964 --- Comment #7 from Peter Grehan <grehan@FreeBSD.org> --- The root cause of this issue was a bug in the XHCI TRB processing loop, whi= ch resulted in the back-end control transfer routine being called twice. While this was mostly benign, the GET_STATUS handler did not recognize this case = and assumed a valid data pointer. I have a patch for this that I'll put up for review. The NULL derefs will be fixed in a follow-up commit. --=20 You are receiving this mail because: You are the assignee for the bug.=
