Public bug reported:
I experienced an issue with mounting CephFS shares after upgrading
linux-image to linux-image-4.4.0-1043-aws and/or linux-
image-4.4.0-103-generic.
After rollback and downgrade back to linux-images linux-
image-4.4.0-101-generic and linux-image-4.4.0-1041-aws mounting was fine
again.
While having booted with the updated kernel image and while the mount
error was present (error message on console: input/output error) I
noticed the following logging in syslog - maybe that helps:
