Do you know if I install the kernel Linux kernel 5.15 from PVE 7.4 could work with Proxmox 9.0.3 as pve7.4 and passthrough works well together.

Hello everyone, Hello @jasonwch Same ask, same issue :-) Each time I make modification and when the system doesn't want to boot I need to re install proxmox from the start. If I start with rescue mode, same that stucks somewhere and I can't have on prompt the maintenance mode in typing root...
