I updated the attachments for the latest version I tested.

Also, at the end, the emulator quit with the following error message:

intel_do_flush_locked failed: Input/output error
terminate called without an active exception
Aborted (core dumped)

There were workaround for SKL and improvements pushed in kernel and Mesa that will benefit to your system, so please re-test with latest kernel & Mesa to see if this issue is still occurring. 

In this last case, please attach new gpu crash dump & kernel log (you may add "drm.debug=0xe log_buf_len=1M")

just clarifying: "drm.debug=0xe log_buf_len=1M" should be in your boot command line

Timeout. Assuming that it is fixed by now. If this is not the case, please re-test with latest kernel & Mesa (12-13) to see if this issue is still occurring since there were improvements pushed in kernel and Mesa that will benefit to your system.
