Hello !

I'm relatively new to proxmox, I was installing it for my homelab on two dell R730 servers:

Code:
- Dell PowerEdge R730
- 2x Intel Xeon E5-2699 v3 @ 2.30GHz (72 threads total)
- 768GB RAM (DDR4 2133MHz)
- Dell PERC H730 mini RAID controller (firmware 25.5.0.0) (RAID50 mode)
- iDRAC 8


I have the full TSR file attached to that post if needed (or if you want to do the diff to see what hardware could be the issue)
One of my server booted the ISO and I proceeded with the install.


The other I'm completly stuck:
- The official ISO is provoking boot loops: It says "waiting for /dev to be fully populated"


So I tried installing proxmox via debian:
Debian 13 works and during the installation as soon as I need to reboot to boot the Proxmox kernel (Linux 6.17.13-4-pve), It won't work and start bootlooping again.
Debian 12 works perfectly and I successfully managed to convert It to Proxmox 8. But As soon as I migrated to Proxmox 9 it started bootlooping.


So I did hardware tests:
- Ram seems fine (memtest86+)
- CPU seems fine (stress-ng)


And I did some tweaking with kernel parameters to try boot the kernel anyways.
It was unsucessful and I would love to post screenshot and have advices if it's the right method to get the solution.


I would love to have your opinion on the right methodology to go forward to have my installation done.
