It looks like those errors were probably caused by I/O errors while
writing to the journal. Maybe due to a flakey USB connection,
perhaps? It would be useful to look at the /var/log/messagfes around
that date to get a more detailed look.

Yes, errors that get recorded into the superblock are also errors that
would cause a read-only remount if the file system is set that way.
