 I issued
 # sysctl -w ddb.commandonenter=trace
 in single-user mode and resumed the boot. Iâ??m
 afraid the output (attached) is not very helpful.
 
 When running the patched kernel, there were two diagnostic printouts.
 One happened just after outputting the modules path and ended
 with a â??doneâ?? line. I didnâ??t capture it before the VT switch.
 
 The second one seems to be more interesting.
 Youâ??ll find the transcription attached.
 
 Was the change from vp->v_mount to vq->v_mount
 intentional? Iâ??m asking just in case.
 
 Thank you for your prompt response.
