I'm using Arch linux. As you know, each new update can bring troubles to the system and i think that happend to my system. For few weeks now sometimes i can't reboot / shutdown my system properly - when i click "Restart" or "Shutdown" from my "XFCE 4" menu, GUI is reduced to console (like while boot), each process is stopped (one by one) and system halts in the end. The problem is that sometimes, when i get dropped to console after i click reboot / shutdown, only text that is written is "login:" (like when you try to login from console) and that's it - system is freezed because i can't type anything (like keyboard is turned off) i can't do anything except manually reboot my system.
What might be the problem? How to solve it? System worked fine for several months after i installed it, i haven't added any new hardware since then.... i simply have no idea what might be wrong... Can "hd-idle" cause those problems? (My Arch is on SSD, and i use "HD-Idle" to stop my regular hdd).
