Im having problem with reboot.
I can halt ok, like the pc shutdowns and power off ok
but when i do reboot, it says rebooting system but it hangs for a very long time, and i have to hard reboot it.
This situation never happened before i did a pacman -Syu.
I've upgraded to the latest kernel 188.8.131.52 via pacman
I have the same problem on 2 computers. I was able to solve this on one by disabling APIC in the bios. On that computer because there was a segfault and a message about 'no more processes at this run level'. On the second it just hangs at the end of the stopping services list. I am running 184.108.40.206-mm4 and 220.127.116.11 with udev.
Well downgrading from 18.104.22.168 helped with the reboot problem
