>From the upstream discussion thread it looks like I was on the right
track (https://marc.info/?l=linux-netdev&m=155688404826002&w=2). For
confirmation I am building another set of test kernel packages and once
this can be confirmed will proceed to SRU this into the other series.
This looks to have remained unnoticed so far, so anything after 4.18 and
all the older kernels which have backported those changes would be
affected.

Bug description:
  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.
