Proxmox - Troubleshooting - Kernel Panic

NOTE: As the Kernel Panic seems to coincide with IO load, another option is to try disabling io_uring.

• With “cache=writeback” that is already the case, so it would seem to be a candidate of something that clearly changed in PVE 7.0.

• To test, edit the VM config in /etc/pve/qemu-server/<vmid>.conf:
  • Add ,aio=native to the end of your disks (i.e. scsi0, sata0, etc…).
  • Verify by making sure qm showcmd 100 --pretty | grep io_uring does not show anything.
