Thanks for the updated Kernel. Sorry for the late reply. Changes of ipmi where without success.
However I could install and boot your kernel Linux version 4.4.0-144-generic (smb@kathleen) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10) ) #170+lp1824687v1 SMP Tue Apr 30 11:18:53 UTC 2019 (Ubuntu 4.4.0-144.170+lp1824687v1-generic 4.4.176) I activated IPv6 Traffic. We should see if the machine will panic. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1824687 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.
