Bug ID: 141741 Summary: drm:radeon_get_bios [radeon]] *ERROR* Unable to locate a BIOS ROM Product: Drivers Version: 2.5 Kernel Version: 4.6.4 Hardware: x86-64 OS: Linux Tree: Fedora Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: baygon@alrj.org Regression: No

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.

--- Comment #13 from Michael Schenaerts baygon@alrj.org --- 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.

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 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

If I remove the changed line in the source of v4.6 everything works normally.

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.

--- Comment #22 from Valentin QUEQUET valentin.quequet@gmail.com --- 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
