Bug#838544: ext4: ext4_iget:4476: inode #8: comm mount: checksum invalid

[Stefan Fritsch <sf@sfritsch.de>]

Package: src:linux
Version: 4.7.4-2
Severity: grave
Justification: renders package unusable

When booting with linux-image-4.7.0-1-amd64 4.7.4-2, one of my
filesystems fails to mount with:

ext4_iget:4476: inode #8: comm mount: checksum invalid

A fsck does not find any errors, though, and the mount problem persists.
After rebooting with 4.6, it works.

It seems this is a known problem:

Not sure about the severity, but I thought I should prevent it from
migrating to testing until you have looked at it.
