stubled across https://bugzilla.proxmox.com/show_bug.cgi?id=5926 which mentioned kernel-issues related to the 8.3.0 release - so took a quick look.
While I think that the issues were not directly related to 8.3 (or the kernel version shipped with it (see bugzilla)) - one issue seemed to be easily addressable with a cherry-pick from kernel.org stable-6.11.7 (patch 1/2) the second patch addresses an unrleated issue reported in our forums: https://forum.proxmox.com/threads/.157266 see the commit-message of the patch for a bit more information - but it basically reverts a patch from Ubuntu-upstream, as this broke iGPU passthrough for old Intel-CPUs (without the patch users affected by the issue reported to Ubuntu had the options of disabling iommu via kernel-cmdline anyways). I'd suggest pulling patch 2/2 also for our kernel 6.8.
