Kernel Null Pointer dereference
-
I am on 8.2.1; uptime 8+ months, no issues.
This is the IPMI screen output (VGA)
Recent history:
I fast copied a Win10 VM yesterday and stood it up for a user.
A tech randomed (wrong IP) into viewing the IPMI output today and pointed it out to me.I checked:
/var/log/daemon.log
/var/log/xensource.log
/var/log/SMlog
/var/log/kern.log
dmesgI don't see any references to a Kernel Bug in any of the logs.
Seems similar to this thread: https://xcp-ng.org/forum/topic/5174/kernel-null-pointer

Check the
dmesg. I'm feeling it's a fixed bug with our updates, since your uptime is 8+ month, you must update and reboot your host. -
Ahh found it. Musta glanced over it when I skimmed through dmesg the first time.
Thank you!

So for the updates. How do I know when I need to install updates? I looked at releases and saw 8.2.1 was latest. Do I need to check somewhere like github?

FYI, system is 100% offline; so I will now subscribe to the update thread... lol
https://xcp-ng.org/forum/topic/365/updates-announcements-and-testingWow. Failure to read documentation. [I tried, kinda]

A good place to stay tuned about updates is our XCP-ng blog. Also, Xen Orchestra is displaying available updates with a "red pill" which is very visible. Aren't you using Xen Orchestra?
-
I do read the Blogs. They're one of the better/best blogs out there
I guess I don't (didn't) understand LTS vs updates vs upgrades.
System is airgapped so Xen Orchestra has no idea there are updates
My long-running goal is to build an edge server VM to clone repos for updates.

LTS doesn't mean no updates. You always need to patch for bugs or security issues
