Same oops with v5.3.1
Same oops, newer kernel.

Previous oops (Same oops with v5.3.1) was triggered by changing the audio
volume. I assume something to do with the volume OSD tickles the GPU.

I was stating to suspect this might be a hardware problem, so I sourced a
similar machine with a Radeon 6770M. Unfortunately the same fault exhibits.

I'm now at a bit of a loss as to how to debug it. I can reproduce it reliably
by playing a 1080p video on each head with mplayer and triggering the OSD
(volume/brightness) changes. I can't bisect it with an earlier kernel because
it doesn't occur when using the internal panel, one Thunderbolt and one HDMI,
and the dual thunderbolt support only turned up in 5.2.

I thought given these generally result in a stack canary I'd try something
different. Upgraded to latest linus-git and disabled the stack protector.
It did take a bit longer to hit, but we got there.

And another one.
Disturbingly in a different location. I'm starting to wonder if there is a
deeper issue at play.

--- Comment #8 from Brad Campbell <brad@fnarfbargle.com> ---
I'm running out of ideas. I assume from the complete lack of interest I'm
either putting this in the wrong place or everyone is concentrating on new
hardware.
Recap. This is happening on two separate and different machines. Both iMac, but
one with a 6770M and one with a 6970M just to rule out hardware failure.
Tried it with dpm off. That made it last a bit longer, but :

--- Comment #9 from Brad Campbell <brad@fnarfbargle.com> ---
Another observation (after another lockup). I have the kernel set to reboot on
panic. On reboot the machine displays a grey screen (as it does on a normal
boot) but never gets to the bootloader.
I have to hard power cycle the machine. I suppose that might imply the card is
getting into a hardware state the firmware can't recover from.
I have observed this behaviour every time it has auto-rebooted. Still booting
with radeon.dpm=0.
.
