This crash is related to a sound patch that was introduced mid February and affected other platforms as well, but now it should be fixed. Christophe, can you check please it is ok now on BXT-P platform?

Hi Jairo, Is this test still failing? Thanks
So looks like it's no longer taking forever, it ends now, find below the Output I get when executing the ./drv_module_reload_basic test: Reloading i915.ko with unbinding /sys/class/vtconsole/vtcon1/: (M) frame buffer device module successfully unloaded module successfully loaded again Reloading i915.ko with inject_load_failure=1 unbinding /sys/class/vtconsole/vtcon1/: (M) frame buffer device module successfully unloaded Reloading i915.ko with inject_load_failure=2 module successfully unloaded Reloading i915.ko with inject_load_failure=3 module successfully unloaded Reloading i915.ko with inject_load_failure=4 module successfully unloaded Reloading i915.ko with module successfully unloaded module successfully loaded again Used the following kernel: commit aedfaaef290af9c8df7d9f4adf22cbe21704d091 Author: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Date: Mon Apr 4 14:10:49 2016 +0100 drm-intel-nightly: 2016y-04m-04d-13h-09m-54s UTC integration manifest However I am not sure why it doesn't show a test status after it's completed...

(success, fail) anything. The above output indicates success but you should also check dmesg for any errors/WARNs. The script itself won't provide the standard success/fail test status message, you'll only get that when executing the test as part of a piglit run. piglit will in turn check the exit status of the script and check for errors/WARNs in dmesg as usual.
