RHEL 8.7 released (November 9th)
- RHEL 8.7 was released November 9th 2022, this blog shows new features with 8.7 too,
- This is the download location for RHEL 8.7
- We recommend using the latest edition of RHEL. You can certainly use either RHEL 9 as well.
RHEL 8.x life cycle goes to 2029 and [RHEL 9.x life cycle goes to 2032 (scroll down at that link)
Those last two links also mention Extended Update Support.

Thanks for the information, RJ ! I've upgraded my systems already, and everything worked as expected ... also, no issues so far. :)

Hi all.
I am not an expert user by any account and use RHEL at home as a desktop computer and for playing around on my local network.
I ran yum upgrade today to keep things up to date as I occasionally do.
The upgrade process itself went smoothly from 8.6 to 8.7 on Kernel 4.18.0-425.3.1, but after rebooting I am getting these "BUG: soft lockup" errors.
The computer is unusable until I power cycle and use the previous Kernel, which was 4.18.0-372.32.1.
The only new errors I've noticed under the older Kernel are "Failed to start Performance Metrics Archive Logger" and "Failed to start Performance Metrics Collector Daemon", which are minor compared to being stuck but annoying because they were not there before.
Could someone try to help me with both problems?
Question 1: Have I found a bug in the new Kernel? If not, what can I do to make it work? I think the log below is related.

Hi,
I've got exactly the same problem, it seems like wireguard-dkms package provokes those issue, could you please help us by publish a kernel patch, or tell to wireguard-dkms dev's to fix their package please ?

I highly recommend using ELRepo's kmod package. The latest version works on RHEL 8.7.
kmod-wireguard-1.0.20220627-3.el8_7.elrepo
One of the advantages of kmod packages is that they are kABI-tracking, meaning they do no require re-building upon each kernel update. If you decide to make a switch, be sure to remove the dkms version before installing the kmod.
nevermind use kmod-wireguard instead from elrepo, install procedure for red hat 8 is here : https://www.wireguard.com/install/
