Hi,

	Sorry no one responded, but while the Bugzilla system is great
for tracking bugs, it's not a good place to call attention to a bug.
In fact, I'm not sure that fs_ext4@kernel-bugs.osdl.org forwards
anywhere sane (I'm checking up on that, though).  In general it's a
good idea by sending e-mail to either linux-kernel@vger.kernel.org or
(preferred) linux-ext4@vger.kernel.org.

	From your description, the ext4 filesystem thought there was
some kind of on-disk corruption or other problem with your filesystem,
and remounted it read-only.  That's consistent with your report of the
messages in the syslog of:

ext4_da_writepages: jbd2_start: 1024 pages, ino 40898; err -30

There should have been something in your logs *before* all of the err
-30 complaints, however.  Was this your root filesystem, or do you
have this saved in logfile in /var/log?  If so, can you search back
for something that occurs before all of the ext4_da_writepages error
messages?
