Comment 28 for bug 1430625

Bug also affects me
This bug comes with a SATA hard drive or wire problem that may be connected ... or not
My pc sometimes refuses to start saying it doesn't find any hard drive.
As i disconnect and then reconnect the SATA wires, pc starts (i see grub)
but now i cant login with Ubuntu because of this error "ACPI PCC probe failed [1.119018] ACPI probe failed \n starting version 219 \n Welcome to emergency mode ... Give root password for maintenance:"

Even if the "APCI PCC probe failed" message may not be main problem, any problem disallowing the pc to boot might be considered as ... critical.

Today error stopped after i've cleaned the SATA Power connector connected to my main hard drive.
