Hi,
I have eventually performed the commit bisect (sorry it took me so long time)
between 3.19.0-16 and 3.19.0-17 as the last was the one where I first had the
problem.
here is git message after last git bisect command :
-----------------
5cfb2705fc0c05b182f523b2aee5143c4b402536 is the first bad commit
commit 5cfb2705fc0c05b182f523b2aee5143c4b402536
Author: Matthew Garrett <mj...@coreos.com>
Date: Fri Apr 24 14:59:01 2015 +0800
PCI: Don't clear ASPM bits when the FADT declares it's unsupported
Communications with a hardware vendor confirm that the expected behaviour
on systems that set the FADT ASPM disable bit but which still grant full
PCIe control is for the OS to leave any BIOS configuration intact and
refuse to touch the ASPM bits. This mimics the behaviour of Windows.
