<pre>When running igt@drv_module_reload@basic-reload-final, the first iteration hits
an assertion failure and any further invocation will hard hang the system.
Network connection is lost, no console output, etc. I'm trying to collect a
crash dump next.
This might be two separate issues, but until confirmed, I think they should be
considered related and handled together. The output of the 2 subsequent
invocations:
