I've got 2 new builds I'm trying to install Proxmox on. The install wizard works fine, and finds the nvme drive. I get all the way through the install wizard, and it fails after 1-2 minutes of starting the install. Both builds are getting the same error: "unable to partition harddisk". See attached screenshot for more details. Installing with EXT4 since it's just a single drive.

Hardware:
Ryzen 5700G
32gb g.skill
Samsung 980 EVO 1TB NVME
MSI A520M PRO <or> ASUS PRIME A520M-A

Both motherboards are on latest bios, and both are A520 chipsets.

Things I've tried:
Formatting at 925gb instead of 931gb
Different USB drives on different ports
Installing 7.1-2, 7.0, and even 6.4 (using dd method via Ubuntu and also Rufus on Windows 10)

I guess I'm the only one running into this issue? Anyone have a similar build? I realize this is fairly new hardware. My only hope is for some fix in the next release. Not sure if that's 7.1-3 or 7.2. Might be something in the 5.15 kernel?

I wanted to post one last update in case anyone stumbles upon this issue.

A few more things that didn't work:
-Another bios update
-Installing Proxmox 7.2
-1TB WD Black nvme
-1TB SK hynix nvme
-using XFS instead of EXT4
-installing Proxmox over Debian
-using nvme in a PCI-e card instead of on-board slot
-numerous bios options/configurations
-adding "nvme_core.default_ps_max_latency_us=0 pcie_aspm=off" to grub (see post below)
https://forum.proxmox.com/threads/w...e-error-detected-samsung-980-m-2-nvme.108162/

I had various luck in installing proxmox, but the system would crash or go read-only in 1-2 days. (sometimes in as little as 15 minutes) My last solution was to buy a 1TB Samsung EVO 870 sata drive. Proxmox installed correctly the first time, and has been completely stable for over a week. My only thought is that there is some bug/compatibility issue with the kernel and the A520/Zen3 architecture. There are a lot of articles dealing with various APCI/ASPM issues with linux and nvme's, but nothing I could definitively fix or implement for Proxmox.
