tab it crash.

Unfortunately blender can be very difficult to use for someone who has no idea about any of that stuff (like me). Can you make an apitrace which reproduces the crash when replayed?
Failing that, can you provide idiot-proof instructions for how to trigger the crash, given that I don't know how to locate tabs in Blender, much less the "material" one? (I don't think I even have a copy of Blender installed either, and definitely low on disk space, so the apitrace way is much more likely to lead to an investigation and perhaps eventual fix.)

this bug hang my system and i can't even go to virtual terminal as it appear in
the system hang attachment
so i cant record apitrace because when i did that the trace file was corrupted
and i cant replay it

This is an apitrace file for blender 2.8 rc1
This bug appear when using evee realtime rendering engine which is OpenGL 3.0+
application and seems that is require a lot of GPU power or maybe some OpenGL 3.0+
functionality in broken in Nouveau.
any way here is the trace file.

replaying this trace crashes glretrace. Can you verify that replaying the trace works for you? And what version were you using to record it?
anyway, I am able to trigger one issue in blender, not quite sure if this is the exact one. I don't even have to press this preview thing, just hovering over it is enough.
Seems like the rendering engine on the GPU hangs...

I use apitrace 8.0 and to replay the trace i use
glretrace -b --sb blender.2.trace
or i use qapitrace and uncheck all the checkboxes in retrace configuration
in it to replay the trace.
The trace is playing fine to me, but when i record it my whole system
hang after opening material tab as described then i poweroff my computer
and restart it and the trace file recorded.
