reply to Hosrt Schirmeier: >Possibly this bug? https://bugs.freedesktop.org/show_bug.cgi?id=102435 >-> Ubuntu 17.10's Mesa 17.2.2 seems to be broken No, the 64 bit kernel works it is the 32 bit build that hangs. Seems like this issue is reported against 64 bit. Could be some hardware specific issues and somehow related but on one system I have that hangs this is all I can say. See https://bugs.freedesktop.org/show_bug.cgi?id=103494 perhaps you will find something specific to i915 hanging only on 32 bit kernel after kernel v4.11 that is related.
