--- Comment #4 from Eric Sandeen ---
I am pretty sure all of those messages will be in 512-byte sectors.
/proc/partitions is in 1k units (just to keep it interesting)
781412184 * 1024/512 = 1562824368 512-byte sectors - also past the sector it's
trying to discard.
I wonder what happens if you try a blkdiscard for the entire device, and see if
you get a failure from it as well. (*** note that this will clear any data on
the device, as it will discard every block on the device ***).
It seems unlikely that this is an ext4/e2fsprogs problem at this point.
