Hi, 

Video is working fine with kernel 4.5.5 but once upgraded to 4.6.4, the video
driver doesn't work anymore.

I'm on Ferora 24 but I had the same problem with Antergos.

How to reproduce : Uppdate the kernel and reboot.

--- Comment #9 from Christian König <deathsimple@vodafone.de> ---
What Michel means is using "git bisect" to find which patch introduced the
problem.

E.g. you do "git bisect start v4.6.4 v4.5.5" on the kernel source and git will
jump into the middle between those two versions.

Then you compile the kernel and test it. If it works you do "git bisect good"
in the kernel source directory, if it doesn't work you do "git bisect bad".

Git will send narrow down which patch was the bad one who introduced the
problem.

I did the bisect with no luck. Evrything was running fine

I built the 4.6 and even the 4.7 with the config files from the 4.5 I set the
other options to default and... it works.

I'll try to build them with the 4.6 config as soon as I have the time.

It may be the same problem as Bug 120321.

At my PC the latest Antergos live-image does work normal although it has kernel
4.7.4. The installed version and every other distros i tried with the distro or
vanilla kernel version has the problem with a kernel version of 4.6 and higher.

I can say that I am also affected by this problem. Same errors as the ones
posted here and the ones posted in
https://bugzilla.kernel.org/show_bug.cgi?id=120321

I tried with different OS's with kernel >4.5 (Antergos and Fedora) and all of
them give the same results. Using the fallback kernel 4.5 for Fedora gives no
problems whatsoever

I'm not an expert, but removing the inclusion of drivers/pci/hotplug/Kconfig
equals to disabling all the HOTPLUG_PCI_* options in the config ("Support for
PCI Hotplug" in menuconfig). You could try disabling those one by one to see
which one causes the problem.

Hello,

You're right Tero Roponen, it is the tree that hides the forest !

I recently opened bug #175391 (
https://bugzilla.kernel.org/show_bug.cgi?id=175391 ) and it was reported by
Michael Schenaerts that it was a potential duplicate of this one (#141741).

Thanks to my determination to inquire in that matter and close this bug, we got
what happened wrong and Bjorn Helgaas wrote a fix.

Bug #175391 Bjorn's patch made it in both mainline (4.9-rc5) and GregKH's
-stable (4.8.9).

I invite you to then carefully read the full thread of bug #175391.

In hope this helps.

Sincerely,
Valentin

Michael, Jose, Lukas, David, Socrates, could you test this with v4.9?  It
includes a change that is related: 
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=16d917b130d7
("PCI: Don't attempt to claim shadow copies of ROM").

If the problem still occurs on v4.9, please attach the complete dmesg log.

Closing on the assumption that the patch mentioned in comment #23 fixes the
problem.

If the problem still occurs on v4.9 or later, please reopen this and attach the
