--- Comment #11 from Ivan Iraci (Ivan.iraci at gmail.com) ---
More or less same problem with an ASUS M4A88T-M/USB3 with an integrated RS880
(Radeon HD 4250).

All kernels <= 4.9.* work fine, all kernels >= 4.10.* exibit frequent kernel
errors such as:
[drm:r600_ring_test [radeon]] *ERROR* radeon: ring 0 test failed
(scratch(0x****)=0xCAFEDEAD)
Video modesetting fails, dri is not working.

Before finding this ticket (and all the similar ones) I began suspecting my
mobo or power supply were broken. But then I downgraded the kernel from 4.13.*
to 4.9.* and all is always fine again.

Please, fix it!
