Reading the source I see that the error occured in xfs_buf_read_map, I
suppose it's when xfsbufd tries to scan dirty metadata? This is a read
error, so it could very well be a simple IO starvation at the controller
level (as the controller probably gives priority to whatever writes are
pending over reads).
Maybe setting xfsbufd_centisecs to the max could help here? Trying
right away... Any advice welcome.
