For those using the Framework 16 or 13 with AMD cpu, note they have finally released a 6.11 HWE kernel, which, since running it, seems way more stable then the 6.8 plain ubuntu 24.04.x kernel.
Check it out : 6.11.0-17-generic #17~24.04.2-Ubuntu
I want to add that the ZFS version shipped with Ubuntu (2.2) doesnt support kernel 6.11 yet.
It works with the default Ubuntu kernel (6.8), but only because of some tweaks from ubuntu.
