Bug description:
Description: Ubuntu 16.04.6 LTS

After upgrading our server to this Kernel we experience frequent Kernel
panics (Attachment).
Every 3 hours.
Our machine has a throuput of about 600 Mbits/s
The Panics are around the area of ip6_expire_frag_queue.
__pskb_pull_tail
ip6_dst_lookup_tail
_decode_session6
__xfrm_decode_session
icmpv6_route_lookup
icmp6_send
It seems similar to Bug Report in Debian.

Intermediate solution. We disabled IPv6 on this machine to avoid further
Panics.
