Opt-in Linux 6.17 Kernel for Proxmox VE 9 available on test & no-subscription

[t.lamprecht]

Kernelchanges should be read at: https://kernelnewbies.org/LinuxChanges
Edit: seems like @BlueMatt was quicker ;-( Thanks for the direct links, could not find them on kernelnewbies.org

I did link them already in the announcement post though

For a good overview of prominent changes, we recommend checking out the kernel-newbies site for 6.15, 6.16, and 6.17.

Update 3 HPe servers... no issue... excellent performance.
It's good see Proxmox try to keep up to new kernel releases...
This meant more compatibility and stability as well...

Thanks

Had one issue today, but I'm not sure if its strictly related to the kernel. Had a windows 11 VM crash with a "Internal VM error". System logs showed the following. I restarted the windows 11 VM and so far so good.

Hi,

Had one issue today, but I'm not sure if its strictly related to the kernel. Had a windows 11 VM crash with a "Internal VM error". System logs showed the following. I restarted the windows 11 VM and so far so good. View attachment 91673

please share the VM configuration qm config ID, the output of pveversion -v and the output of lscpu. Are the latest BIOS updates/CPU microcode installed? Anything additional in the surrounding system logs?

It does not work with NVIDIA vgpu drivers GRID 6.12 drivers, it fails to build. (grid 6.12 builds just fine with kernel 6.14). I know it isn't proxmox specific, just saving some people some time if they are running GRID drivers
