Dunno exactly what it means, but it seems to mean the filesystem
code found some status bit on the disk not set the way it thought
it should be. Certainly raises concerns, eh?
Secondly, sd(8,53) refers to the special file /dev/sdd5. On my box
doing "ls -l /dev/sdd5" results in:
brw-rw---- 1 root disk 8, 53 May 5 1998 /dev/sdd5
and you'll notice it's major and minor device numbers (the "8, 53"
part) match those in the error message, and that the "sd" part of
the error message matches the first two letters of the special file
sdxx. Since it's "sd'd'", I'm left to guess you've got four SCSI
devices (at least) and that this is the fourth one, and it has
at least 5 partitions on it.
I'd unmount that partition and run a full fsck on it. If it recurs
it would indicate some problem worth investigating, possibly hardware,
possibly a kernel issue. Beyond that I'm getting in way over my head.
