[SOLVED] Bug in Proxmox Kernel 6.8.* on HP DL 5** G7 Servers

[informant]

Hi all, in last kernels we have many Problems, We cant use only kernel 6.5.13-5-pve as last working kernel. All newer kernels >= 6.8.* have following error:
...iock error debug interrupt for reason 61 on cpu 0...


system hang up and was not reachable.... only hard reboot with power off works here.

how can we fix it or can proxmox team fix it please?
regards

Intel VT-d was enabled by default (by Ubuntu) on Proxmox kernel version 6.8 and later. Add intel_iommu=off to the kernel parameters to disable it again. Also see "Known Issues & Breaking Changes" in the release notes: https://pve.proxmox.com/wiki/Roadmap#Proxmox_VE_8.2

Have defect boot disk now as kernel set filesystem to read-only. Maybe the orig error was just a follow on one.
