I'm really out of ideas...
Could you try using only the radeon kernel driver, just blacklist amdgpu on=
e.
See if the blender trace hangs and netconsole still doesn't give any warnin=
gs.
See if you can completely disable iommu, when using radeon.ko.
I've asked you at least 3 times to test "export mesa_glthread=3Dfalse&=
quot;, but you
never included it in your list of things you've tried.=20
Same for `export RADEON_THREAD=3Dfalse`.
I haven't asked you, but add `MESA_DEBUG=3Dflush` to the things to test.
Now, if you have run out of things to test. You can try a prolonged experim=
ent,
that might not even bring usable result.
If we had a case that hanged reliably, one thing to do is to locate the exa=
ct
operation that causes the hang.
So, you start `qapitrace` with the blender trace.=20
You then do a binary search for the frame that causes hang. It's done by
"Lookup State" at a frame number, it would replay the trace to th=
at frame. You
start with the full range, let's say [0 - 10000], so you pick the frame from
the middle of that range, in this case frame#5000. If it hangs during repla=
y,
you use [0 - 5000] as interval, if it doesn't hang, then you use the other =
half
[5000-10000] (because the cause of hang mush be there). Then you pick the
middle of the new interval and repeat the experiment.
(e.g. [0 - 2500]; [1250 - 2500]; [1250 - 1875].
Once you locate the exact frame that could cause the first hang, you can do=
the
binary search, but this time on the draw operations inside that frame. It c=
an
help if you set:
"qapitrace->Trace->Options->Only_show_the_following_events-&g=
t;Draw_events".
Now, since crashing to you is kind of random, you might try to disable all
threaded options (all options from above) and run same lookup a dozen of ti=
mes.
If it crashes even once, then it crashes.
Also, be sure to write down the current range, as to not loose it at reboot.
I also strongly encourage you to at least try some other distribution,
something you can start from life-cd or something. Or build your own vanilla
kernel.
