Title:
4.4.0-145-generic Kernel Panic ip6_expire_frag_queue
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Xenial:
Triaged
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.
