Reboot instead of shutdown issue

Recently hit subj issue on 2 PCs, on 2 different distros:

  • ubuntu 12.04 on my sister's nettop
  • current archlinux on my mother's-in-law PC
Here're symptoms: PC shutdowns on poweroff command and then immediately turns on. Sounds weird, right?

It turned out that cause is forcedeth driver (both PCs are based on nVidia chipset). I suspect it's somehow related to WoL implementation (however there's not WoL packets in my network for sure - local segment contains only router + 1-2 PCs). Solution is to 'rmmod forcedeth' somewhere on shutdown path. Can't investigate this issue more broadly, I've no permanent access to those PCs :) But some forcedeth dev is guilty for sure
