--- Comment #48 from Teofilis Martisius <Teofilis.Martisius@gmail.com> ---
Hi, 

I ran two tests over the weekend.

First, I tried booting up stock 4.8-rc4. glxgears runs fine both on APU and
dGPU. But it fails when I try to turn OFF my dGPU by doing:

echo OFF >/sys/kernel/debug/vgaswitcheroo/switch

dmesg output attached.

Second, I modified 4.8-rc4 & removed my computer from radeon_device.c quirks
list (it has RADEON_PX_QUIRK_DISABLE_PX quirk assigned) and rebooted. dmesg
attached. It does bootup but with DRI_PRIME=1 glxgears displays just a blank
window. dmesg still shows the "atombios stuck in loop" error.

I won't be able to run more tests soon as I bricked the laptop trying to
upgrade BIOS. I plan to repair/recover it but it will take a while.

OS being used is Debian/Sid. I used stock kernel from kernel.org, with 1 line
change in 2nd test. Same laptop as before, described in previous comments. 

I hope any of this helps.

Sincerely,
Teofilis Martisius
