[SOLVED] After upgrade from 7 to 8 - Proxmox is not booting anymore

Jun 17, 2021
Hello :)

I've upgraded one Proxmox Server from 7 to 8. After the upgrade the server won't start anymore. There are ACPI errors but I am sure these errors been there sind Proxmox 7 and it was starting with no Problem.

It just halts forever in this state.
ACPI Error: No handler for Region
ACPI Error: Region IPMI (ID=7) has no handler
ACPI Error: Aborting method ]_SB.PMI0.GHL due to previous error

if I disable ACPI with acpi=off while starting it leads direct into a reboot.
The PVE Gui is never loaded and the network is not started
Also it seams that there is a zfs pool missing or not started
I can start the rescue mode an log on but don't really have an Idea what to do or where to start debiggung

Do you have other Kernel options in your bootloader you can try?
Yes I can start into the rescue shell


no zpool but I can handle that when pve is starting with network again :)

`journalcontrol -b` - sorry I can't copy 'n paste due to limited remote console


this is bc the recovery mode right?


all disks

It looks like your BIOS and your IPMI is out of date. Can you update them?
Bom dia pessoal estou com o mesmo problema que o colega acima, porem nao posso formatar o pve, alguem conseguiu resolver?
Consegui resolver pessoal, única coisa que precisa ser feita é identificar qual kernel esta utilizando, entrar em modo recovery e rodar
# apt install --reinstall pve-kernel-(Versão do kernel)
# update-grub2
