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

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