Many thanks for your feedback. I forgot about Magic SysReq and this helped me a lot to resolve this issue: 1. First I set sysctl kernel.sysrq=1 to enable alt+sysrq 2. I've set kernel log level to 9 using alt+sysrq+9 3. Poweroff was way more verbose now. Last line on screen was: Preparing to enter system sleep state S5 Using google I found this: https://bbs.archlinux.org/viewtopic.php?pid=1014214#p1014214 Resume by PCI-E was enabled in bios. After disabling it my system can power off again. Thanks! Łukasz
