Comment 29 for bug 1430625

Rebooted my main pc, first time in long time and got this error. Unable to reach desktop using either Nvidia, Nouveau and even pulling GPU and using Intel off mb. Not sure if related but getting sysctl errors also tried reinstalling systemd and even switching to upstart but both fail to reach reach desktop and hangs on acpci failure. Old kernels fail also. I keep correcting a no libgpg.so.0 version error but it won't hold between boots. Ubuntu 15.04 64bit gigabyte Z97X-UD5H-BK mb 32gb ram i7 4790K. MB and devices check out fine and live stick works fine. Hope some of this is of any use.
