Stable kernel 6.4.3 (and 6.3.13) released [LWN.net]

The 6.4.3 stable kernel has been released; it contains a handful of fixes, mostly for problems associated with the per-VMA locking code. Anybody running 6.4 probably wants this update.

Note that there is a much larger 6.3.13 update going through a longer-than-usual review process that should show up soon.

Update: 6.3.13 is now out. Note that this is the last 6.3.x update.

The 'stable' kernels seem to have been rather unstable recently. I've had problems since 6.3.10 onwards (everything up to 6.3.9 was fine), on my AMD Ryzen system. Not sure if it's all this VMA locking stuff, or amdgpu driver stuff, but I think I'll stay away from 6.4 until it settles down a bit....

Was in a similar boat to you (AMD Ryzen system(s) with AMD GPUs, having some shenanigans since 6.3.10) and I'm running 6.4.3 without any glaring issues. Note that there were external factors that may have been "the" cause for our instabilities (esp. if you run Arch Linux):

Botched graphics firmware update from AMD
Botched/buggy changes in early-boot firmware handling (compression) in Arch Linux (compounded by the fact that upgrading the firmware package doesn't automagically regenerate the initramfs files)

In my specific case, my desktop PC (Ryzen 3900X, AMD 6700XT GPU) would sometimes shutdown and restart on resume from sleep, and my notebook (HP notebook with a Ryzen 3200U CPU) would kernel panic more than half the times I tried to boot it, usually after I decrypted the rootfs :(. The only times I managed to see something in the logs it would point to the USB subsystem...

PD: On my notebook I bit the bullet and installed linux-lts (6.1.x as of this writing) which fixed the kernel panics, but I can't shake the feeling it was mostly due to a fresh initramfs.

In my experience 6.3.8 was the last stable kernel on Ryzen 7 5850U with integrated amdgpu.
6.3.9 was profoundly broken.
6.3.10 not much better.
6.3.11 almost good and 6.3.12 I had no problems although some Fedora amdgpu users reported it was still broken.
6.3.13 backported a bunch of stuff from 6.5 and broke things again in a different way. It is unfortunate it is EOL.

6.4.3 seems almost good here.
