[Bug 1349740] Re: acpi PNP0A08:00: _OSC failed (AE_ERROR); disabling ASPM


Same issue on stock Dell Inspiron 17R SE 7720, Ubuntu 14.04 w/EnhanceIO
ssd caching, Win 7 w/Intel iRST ssd caching, Linux 3.17.4 kernel.

An hour of googling led to kernel parameter pci=nocrs without any change
except, clearing up the message "kernel: [    0.211061] PCI: Ignoring
host bridge windows from ACPI; if necessary, use "pci=use_crs" and
report a bug"

In google circles David Rientjes, Rafael J. Wysocki and Jiang Liu touch
on this issue but only a patch for ACPI CPU errors was released (as best
I can decipher).

A few bug reports were issued for "kernel: [    0.216171]
\_SB_.PCI0:_OSC invalid UUID" this year but expired because another user
didn't confirm it.  FTR this error also exists in my /var/log/syslog.

Hopefully these annoying messages can be suppressed because whilst one
is looking for a REAL error these ones send him/her down a rabbit hole
require hours of goggling update-initramfs and reboots only to discover
a false-positive and move onto the next trial & error repair option.
