Proxmox 4.1 will not reboot server, kernel 4.2.8-1

[jinjer]

Hi,

There's an issue with the latest proxmox 4.1. It will not reboot the servers (my servers at least), but will just stay in the "shutdown" state:

To reproduce:
#reboot
....
...
Server has reached shutdown state.

pveversion -v

MB is Supermicro SYS-2027TR-HTRF+
AMI Bios.

It was working before with all proxmox, up to 3.4

Hi,

I think before somewone can say somethink in detail you have to look at you log-files and in dmesg
at the time the server stops to come closer to the problem…..

Might be a common problem, actually. I have some other servers, different bios and mb, with same behavior.

But like I say, it does the correct shutdown sequence but no reboot. Stays in "shutdown state". This is something kernel related (perhaps acpi) and was working fine in proxmox 3.4 and kernel 2.6.xx

Will try to post screenshot later.

I'm attaching the last thing shown on the console (dmesg cannot be captured on this srv, sorry).

The server (and other servers) stay on until manually reset. The other server with the same problem is a Supermicro X8DTT-H MB.

Sorry, the issue seems related to the lockup here: https://forum.proxmox.com/threads/pve-suddunly-stopped-working-all-cts-unrecheable.26458/

trying to reboot a normally working server works. Trying to reboot a server which was locked up (possibly) by lxcfs will fail.

I have now reverted to kernel 4.2.6 on some servers to see if the older kernel is more stable.
