(#219074 is similar in subject, but stack trace is different).
Today I wanted to record a CDRW, I inserted a non empty one (which I intended to blank) and my system crashed.

Possibly devd or some other component (from XFCE?) tried to access the disk, alhough I didn't ask to mount it in any way.
Notice this is my first multi-user boot after the upgrade to 11.2-RELEASE-p11: this might be related or not to FreeBSD-SA-19:11.cd_ioctl, but it never happened before.
I don't believe this is related to the SA.
Could you provide the core.txt from this crash?
I've tried attaching it several times, but connection always times out.
Please, find it here:
Notice I've made some other tests and was unable to reproduce this crash again.

Thanks. My guess is that this would be fixed by r323977, which is unfortunately not present in 11.x. If you're able to test kernel patches, please try the attached diff.
