[Eneko Lacunza]

Hi all,

This morning a proxmox server installer two weeks ago has rebooted 
spontaneously. Last entries in syslog are:

Oct 29 12:18:04 proxmox2 kernel: Uhhuh. NMI received for unknown reason 
2d on CPU 0.
Oct 29 12:18:04 proxmox2 kernel: Do you have a strange power saving mode 
enabled?
Oct 29 12:18:04 proxmox2 kernel: Dazed and confused, but trying to continue
Oct 29 12:22:47 proxmox2 kernel: imklog 5.8.11, log source = /proc/kmsg 
started.

Any idea what to do about it? It's on production now and I can't "play" 
with it :)

Thanks
