Thanks for the update.
Looked up the phoronix reviews and saw this. SLAB is deprecated.

FWIW: Just built and installed the 6.8.0 kernel. It is early yet, but so far, so good.

6.8.0 ran almost fine for me, I always test new kernel releases with a sleep and resume test a few times and run some games. I kept getting this message spaming my logs and dmesg output.

Code:

[drm] scheduler comp_1.0.1 is not ready, skipping

I had hundreds of those lines in the course of in hour testing the new kernel and a sight but noticeable slowdown in desktop performance.

back to kernel 6.7.9 and all is back to normal.

Thanks for the heads up.
As I don't own or use a laptop/notebook I haven't seen any problems, as of the moment, with the 6.8.0 kernel on this box.
The 6.6.20 kernel worked just fine for me, but there were two spontaneous reboots with 6.6.21.

I'm using a desktop atm, I just find running a couple suspend/resume cycles on new kernels tends to be the best way to stress the kernel OOTB and if the system does come out of suspend without any gotchas that usually means the kernel is going to be relatively bug free on my system(s). It's just a one part of anecdata and one part ritual that I have been using for the last few years.

And most of the time when the test fails and couple kernel point releases fixes the issue(s).

After retesting kernel 6.8.0 I noticed my Windows partition wasn't getting mounted at boot and also I could not mount it manually so I make oldconfig the kernel config from 6.7.x again and found that the new kernel option

Code:

BLK_DEV_WRITE_MOUNTED

needed to be enabled. After a recompile the partition showed up again. Just a heads up for those that use the FUSE NTFS-3g driver with the new kernels.

6.8.1 seems to be specifically addressing another CPU vulnerability, in Intel Atoms this time. I'm building it now, but I don't have an Atom so to be honest, I'm not sure why I'm bothering to do so.

There is also a new Intel microcode release (20240312) needed to mitigate the vulnerability in addition to this kernel.

do you have the same security problem with kernel 6.21?

Security problem ??

It seems to be just a warning

Edit in: The "blackout" is now 9 seconds with the 6.6.20 kernel.

This seems an intermittent problem across kernel releases.

I was running 6.7.2 kernel (Slackware 15.0) with "only" 2 seconds, it's acceptable.
Now with 6.8.1 the 6 seconds blackout is back.
6 seconds for us "computer guys" is long enough to be irritating.
Anything more than 10 seconds is an eternity.

This is with NVidia driver 535.154.05, but it doesn't matter.
The blackout happens with any version.
IIRC it happens with nouveau too.
