Discrete Radeon videocard is missing with kernel 3.13

[Anton Sudak]

Discrete videocard is missing linux 3.13. There no /sys/kernel/debug/vgaswitcheroo and xrandr --listproviders shows me only Intel videocard. Videocard also missing in lspci output. There are some traces in dmesg which can be related to this bug. The last working kernel version for me is 3.12.9.

00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Turks [Radeon HD 7650A/7670A]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.13 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

If the bug still exists in 3.14-rc1, we can perform a reverse bisect to identify the commit that introduced this regression.

Joseph,

I already tried to bisect kernel, but part of kernels hangs at boot and I was unable to get any results. At mesa bugtracker I found workeraund, if I disable CONFIG_HOTPLUG_PCI_ACPI option in kernel config all start to work fine.
