I had occasion to try this patch (downloaded on June 19) on my Xen dom0 today, 
and things didn't go well;

# ccdconfig -c ccd0 0 /dev/zvol/dsk/internal1/photos@backup
ccdconfig: ioctl (CCDIOCSET): /dev/ccd0d: Read-only file system

...and a subsequent...

# ccdconfig -g

...instantly rebooted the system (no crash dump). I wasn't monitoring the 
console so I don't know if any error was printed by the kernel. Nothing was
recorded in syslog.

This is NetBSD 9.0_STABLE from June 19 (built at the same time as the patched 
z, with xen 4.11 (4.11.3nb2)
