I have a Dell Inspiron with a Radeon R7 M260/M265 [Topaz XT] - as reported by lspci, and I'm facing problems with GPU initialisation, rendenring it unusable, it is not listed on `xrandr --listproviders`, for instance, althoug the driver is properly loaded. Attached are `dmesg` and `lspci -k`. Please let me know if there's something else I can do to help.
Thanks for any help,

I wouldn't call this "properly loaded", the kernel driver completely fails to initialize the hardware and unloads itself after realizing that this won't work.
Good to know that unloading the driver works, but I don't have any idea what's going wrong here.
@Alex: How well did we already tested Topaz? If not we might want to disable the PCI-ID for now.
Well, I've said "properly loaded" because `amdgpu` is listed on `lsmod`.

We haven't really tested them much. How about the attached patch?

Yeah, probably a good idea until we have time to fix those.
Patch is Reviewed-by: Christian König <email@example.com>
Is there any Progress with this Bug? I've a Notebook here from a project, where the Official Driver could not be used currently (Xorg 1.18)
I'm also experiencing this bug with a Radeon 6850 and GNOME 3 desktop, on following systems:
Ubuntu 14.04 with 3.19 kernel and fglrx drivers.
openSUSE Leap 42.1 with open source drivers.
It happens when I resume from suspend. System hangs and switching to tty1 displays all the errors such as "ring 0 test failed", etc. From there, I have to shutdown the system if I want to use it.

Different GPU => file your own report please.
I can confirm that issue is now gone, using Linux 4.5 (which contains dba280b20bfd1c2bed8a07ce3f75a6da8ba7d247). Who does take care of closing this issue?
Resolving per comment 10, thanks for the followup.
