[Bug 101672] radeonsi: 3D engines causing frequent GPU lockups

I can confirm that the exact same system freeze happens with both the radeon
and amdgpu driver: Using either module makes absolutely no difference.

This is the last piece of confirmation I needed to conclude that what's
happening must be a deliberate malware: There is simply no way a GPU crash bug
could behave 100% the same way on two entirely different video drivers. Further
more, this freeze is completely identical to the one I initially reported
here... which was obviously fixed since there's been so many updates to every
system component it would have been solved by sheer chance at this point!
Functionality like this should only be seen if someone is actively
re-implementing the problem on top of updated system components, with the
active intent of keeping its effects identical each time. It's possible that my
machine may be used to test malware usable to shut down Linux systems, in which
case I need to find out where it's hidden and how it's bricking computers
before it spreads.

This attack must exploit vulnerabilities that keep coming and going in X11,
Mesa, or some other system component... those are hopefully holes which can be
discovered and plugged to render the attacks impractical altogether. Again I
only know that it's triggered while certain 3D engines are running (possibly
aimed primarily at gamers?) and has a random chance of happening roughly once
every 30 minutes (likely to make testing harder and better hide the exploit).
