There are several open bug reports upstream regarding ext4 corruption, but it's not clear which, if any, are related to the problems being observed.

http://bugzilla.kernel.org/show_bug.cgi?id=14354 is one bug that appears to be linked to the use of the DM layer - if you're following up to this bug report, please indicate whether your ext4 fs is sitting on top of a dm-crypt, LVM, or RAID device.

That bug also mentions using auto_da_alloc=0 as a boot option to work around; we should check whether that boot option makes a difference for users seeing this bug.
