Comment 0 for bug 1824687

Description: Ubuntu 16.04.6 LTS
Release: 16.04

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.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=922488

According to the bug finder of above bug it also occurred after using a Kernel with the change of
rewrite ip6_expire_frag_queue()

Intermediate solution. We disabled IPv6 on this machine to avoid further Panics.
Please let me know what information is missing. The ubuntu-bug linux was send. And I hope it is attached to this report.
