loading initial ramdisk hang, after reboot

[Thomas@phase]

I have a full pve envirement running with 3 nodes with block storage ceph for HA with packet (bare metal). The cluster was running great. Today i was working on an overlay network and after every change i rebooted the server (call me lazy). After 5 or 6 reboots the serer hang during boot. Packet has a rescue ssh solution for this, so i could see what the server does during boot, the only thing i saw was:

Loading Linux 4.4.35-1-pve ...
Loading initial ramdisk ...

I can acces the grub commandline. I tried several kernel options like "nomodeset", and also booting manually. It looks like the initrd or kernel has a problem and cant boot.

Are there other solutions i can try before deleting the server?

Can you boot an older kernel? When please upgrade system to newest kernel 4.4.35-2. There was a bug on your version, had nothing to do with your problem, but you never know: https://forum.proxmox.com/threads/p...cess-8543-kvm-score-or-sacrifice-child.31569/

If i acces the /boot folder, the following files are present:

grub/
initrd
vmlinuz
vmlinuz-4.4.35-1-pve
config-4.4.35-1-pve
pve/
System.map-4.4.35-1-pve
initrd.img-4.4.35-1-pve

Where would other kernels be located?
I can't upgrade, because i don't have a valid subscription yet. and updating with a broken kernel is kinda hard

Then please boot with an livestick enter the chroot and check the system like this:

apt install -f

Use the proxmox no subscription repository to update to current kernel. HW is ok? HDDs/SSDs... Memory...

I tracked down the issue to a wrong network file.
I have Openvswitch running along with the networking.

A wrong configuration in the /etc/network/interfaces was the problem, this created the hang.

Thnqx for the fast reply
