--- Comment #4 from Conrad Meyer <cem at freebsd.org> ---
Petr,

I suspect when CAM sees EROFS or EIO errors due to write requests to read only
media failing, it ejects the device.  Something about the ejection path is
failing to clean up references to some internal object, which is freed before
buffers referencing it can be released.
