Yea I am testing 6.1 heavily and so far its working great. 5.19 isn't being updated anymore from my understanding so its not an option for us.
5.15.x Kernel and Issues
- Thread starter adamb
- Start date
Just wanted to mention.
While getting some front ends moved to 6.1.x, I hit VM lockups on every VM going from a DL 560 Gen10 with 5.15.83 to a DL 560 Gen10 with 6.1.2-1. Both servers are identical. Once both were on 6.1.2-1 all was well.
Appears to be more than just a generation issue for live migration.
Either way 6.1.2-1 seems solid so far, but I wanted to mention it.

Ended up running into a significant CPU performance isssue on the 6.1 kernel. Looks like we will be forced back to 5.13.x at this point. What a mess.
maybe retbleed mitigation ?

(Not sure if it's still buggy in 6.1 and fixed on 6.2)
