Public bug reported:
Using Ubuntu 12.04 server, we installed a machine using the following disk
layout:
XFS => dm-crypt => RAID5.
A *complete* list of ALL configuration of the machine including the
setup can be provided if you need it, we documented everything.
The harddisks are tested weekly with a full SMART test and they are okay.
The machine is attached to a UPS and therefore never suffered a hard reset.
Also, the memory was tested with memtest86+.
Nevertheless, the kernel crashed in ext4:
