Title:
skb_warn_bad_offload Crash
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Xenial:
Fix Released
Bug description:
We're setting up a new Dovecot server on Xenial. When we start the
migration of emails, either the IMAP traffic or the NFS traffic
immediately reproduces the crash below.
I bisected using the mainline kernels. Everything up to and including
v4.5-rc7-wily fails, but v4.5-wily works.
