Something in this series of commits is causing the GPU to hang on reboot
on my Dell XPS 8300 machine. That has a:
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee
ATI Caicos [Radeon HD 6450]
card in it. After reboots, I get a screen that looks like this:
http://t.co/tPnT6xQZUK
I can hit it fairly consistently after a few reboots, so I tried doing a
git bisect on the radeon driver and it came down to:
ca57802e521de54341efc8a56f70571f79ffac72 is the first bad commit
commit ca57802e521de54341efc8a56f70571f79ffac72

drm/radeon: halt engines before disabling MC (6xx/7xx)
It's better to halt the engines before we disable the MC.
Signed-off-by: Alex Deucher <alexander.deucher@xxxxxxx>
Basically what seems to be happening is drm:r600_ring_test fails the ring
0 test and disables GPU accel. Things go downhill from there, as the
driver continues to try and set hpd after the interrupts have been
disabled already. The relevant dmesg portions are below.
I think Alex has a patch to not do that and I built a kernel with that and
the splat went away, but the actual problem of the rainbow static screen
still remains.
I can send the bisect log if people are interested. I'll try reverting
that single commit and seeing if it fixes things on a known "bad" kernel.
I'd be happy to try further debugging suggestions if this doesn't make
sense.
