Debian's xserver-xorg-video-amdgpu bugscript output

Dear Maintainer,

di.fm's f2p streaming service is now only available through their website --
the downloadable playlist steams that used to be available now redirect people
to the website -- and as a result I pulled up di.fm to attempt to play one of
their steam. But instead of music, I see that the flashplugin has apparently
crashed and a general protection fault pointing to libdrm_amdgpu has occurred
and is reported in dmesg:

[21182.057540] traps: plugin-containe[32761] general protection ip:7f33d2ce0148
sp:7fff24852d60 error:0 in libdrm_amdgpu.so.1.0.0[7f33d2cdc000+7000]

Attached should be the output given by debian's xserver-xorg-video-amdgpu
bugscript

xorg.log

The debian bugscript seems to still use xorg logs from /var/log so here is a
current one from .local/usr/xorg

We need to see a backtrace of a crash.

gdb captured backtrace of segmentation fault

So it turns out I am able to stream successfully from di.fm, I think I may have
just needed to sign up(!) :-)

Regardless though, launching of the web player does seem to be a bit spotty.
Though I'm not sure if it caused by this bug or something else...

I was able to get the attached backtrace by attaching to the browser's
flashplugin subprocess! Hopefully it does help. To reproduce, all that seems
necessary is to visit di.fm.

Not sure exactly which package provided the fix, but now I'm no longer seeing
the fault, and also the stream on di.fm launches more consistently now.
Recently updated packages and versions:

libdrm: 2.4.66-2
mesa:   11.1.1-2

Thanks to all working on this! :)

Closing this bug
