I have problems suspending and shutting down Lenovo G560.
Suspend problem: after suspending neither power indicator, nor power button begin to blink. Capslock and Numlock leds don't turn off after I hear "tsk" sound(probably HDD turning off). Pressing buttons(power button as well) doesn't resume OS.
Shut down/rebooting: Windows, Linux, boot order, bios setting everything freezes for 1-3 seconds, then shuts down/reboots. Linux shows message
Failed to finalize file systems, DM devices, ignoring
I'm not sure if this is the cause, but these happened after installing Hackintosh.
