Assuming my machine is fine =E2=80=94 since reverting that commit resolved = the issue =E2=80=94 I believe the reason there are so few reports is that Proxmox still ships w= ith kernel 6.8. We had an opt-in for 6.11.11, and it also works fine. Recently, 6.14 was offered as an opt-in, and that's what led me down the ra= bbit hole. I started compiling vanilla kernels: 6.12.25 LTS crashed, and 6.12-rc1 crashed as well. This indicated that the problem was introduced between 6.1= 1.11 and 6.12-rc1. I performed a bisect, which led me to the problematic commit. After reverti= ng that commit, I can now run 6.14.4 without issues, just like 6.11.11. Regarding Proxmox VM guest configuration. Proxmox does not use libvirt but I leave the VM configuration file bellow.
