I also tried DEBUG mode.

Below, the output from debug boot log:

```

It starts and hangs.

Here is logs:

And when I attempt to boot from Proxmox 9.2 ISO in the console mode:

KERNEL PANIC!

any idea why is this happening? I'm hving the same issue

1. I think that because of NovaCore, the Proxmox 9.2 doesn't work with Nvidia RTX cards. `nomodeset` doesn't help.

2. In some cases, during upgrade, something is failing / misconfigured with the network stack, so even SSH access is not available on upgrade.

Ok the fix was fairly easy : Scroll down to the line starting with linux. Press the right arrow key to go to the very end of that line, and add nomodeset (ensure there is a space separating it from the previous parameter).
No other changes needed, system started normally

using nomodeset worked for me

Seems like 9.2 is having serious issues for everyone running RTX cards. I wonder if it's happening only on systems that don't have an iGPU?

Installed Proxmox from 9.1 ISO:

Code:

uname -a
Linux t7960 6.17.2-1-pve #1 SMP PREEMPT_DYNAMIC PMX 6.17.2-1 (2025-10-21T11:55Z) x86_64 GNU/Linux

Then switched to `no-subscription` repo and upgraded:

Computer rebooted, printed few boot lines and stopped the output (screen frozen).
However, now web-access and SSH-access is working:

Code:

uname -a
Linux t7960 7.0.2-6-pve #1 SMP PREEMPT_DYNAMIC PMX 7.0.2-6 (2026-05-20T08:55Z) x86_64 GNU/Linux

But on-screen, I can't access terminal.

see the diff for `dmesg` output for 6.17.2 vs 7.0.2 kernel on that workstation:

https://gist.github.com/SlavikCA/99e1f922e511f04f2b60f38cc542ec15/revisions

Code:

lspci -nnk | grep -A 2 -i nvidia

ac:00.0 VGA compatible controller [0300]: NVIDIA Corporation AD102 [GeForce RTX 4090 D] [10de:2685] (rev a1)
    Subsystem: NVIDIA Corporation Device [10de:1697]
    Kernel driver in use: NovaCore
    Kernel modules: nvidiafb, nouveau, nova_core

After over 10 hours of troubleshooting and having to dig through a bunch of docs...

Still no clue why RTX cards are freezing up on the installer even with nomodeset on the 9.2 install. 9.1 install with nomodeset will complete the install and run successfully. Updating the following files:

/etc/apt/sources.list.d/ceph.sources
Types: deb
URIs: http://download.proxmox.com/debian/ceph-squid

Then running your commands, I am able to run the latest version. The console does still hang but SSH/web works. No idea how to fix the console but at this moment I don't really care. Hopefully someone at the dev team can figure this out and issues a patch. I would expect a lot more complaints rolling through as this seems to be a fairly large problem.
