Hi Alejandro,

We fixed a number of GPU hangs on Skylake systems recently, in Mesa master.  I
bet that commit df13588d2176dcf4800a882d926f389667772b46 would fix your hang. 
These fixes should be making their way to 17.3.4.

In the meantime, you could try building Mesa master.  You may also be able to
avoid the hang by exporting INTEL_DEBUG=norbc before starting X.
