Error preparing initrd: Bad Buffer Size

I have just hit this issue also today on an oldish Supermicro MB, is there a v8 installer that works yet?

I'm not aware of any plans to release a new version of the 8.0 installer. What you can do is:
  • Installing 7.4 and upgrading
  • Debug install of 8.0 with upgrading the systemd packages and reinitializing the ESPs before reboot (see the previous few posts)
  • Wait for 8.1

For what it's worth, I would add that I have experienced this issue on a Dell Poweredge T410 and I couldn't even boot the installer in debug mode. I installed 7.4 and upgraded.
I am using a Powered R820 and have the same problem. Had to install 7.4 and upgrade.
When trying to install 7.4 and upgrade, I ran into a different issue, but was able to successfully install 8.0 by following the debug shell method outlined earlier in the thread.
  1. Installed proxmox with GUI in debug mode, entered the shell after installation, then ran:
  2. wget -O /etc/apt/trusted.gpg.d/proxmox-release-bookworm.gpg
  3. Added proper repositories to /etc/apt/sources.list and /etc/apt/sources.list.d/ceph.list
  4. apt update
  5. apt upgrade
  6. apt install systemd-boot
  7. proxmox-boot-tool init /dev/sda2
  8. proxmox-boot-tool init /dev/sdb2
  9. proxmox-boot-tool reinit
  10. proxmox-boot-tool refresh

and it now boots just fine!

I've tried this also like @lugnut (i wanted to write the steps, then the forum told me there are new messages, lol) and it worked like a charm on my Poweredge R720xd with the Dell PERC H710P D1 Controller in IT mode.
