Thank you.

Please note that if I run a kernel build with:
"git reset --hard f7fec032aa782d3fd7e51fbdf08aa3a296c01500"
(the commit before d100eef24) I get a different but similar error:

EXT4-fs (sda): error count: 4
EXT4-fs (sda): initial error at 1361983458: ext4_find_dest_de:1657: inode 70911401: block 15213579
EXT4-fs (sda): last error at 1361983663: ext4_find_dest_de:1658: inode 70647809: block 14164000
