this message means that there was some file data cached in the kernel,
and the i/o to write that data to disk failed, so that data was lost.
the error was 45, which is "EOPNOTSUPP".  I don't know what that error
means in this context, and I've been getting the same error myself
with a 1.5T-vintage kernel, but I thought that was due to some other
changes I've been working on.  I guess it's not that after all.

do you have a way of triggering this problem on demand,
or is it an occasional thing?
