Steps:
------
1. Launch igt with command (as root):
${IGT_DIRNAME}/scripts/run-tests.sh -t igt@drv_module_reload
2. The test start

Actual result:
---------------
2. The test never stop (no timeout) but the system don't crash, and no error found in /sys/kernel/debug/dri/0/i915_error_state

Expected result:
----------------
2. The test is successful (eventually set to fail/timeout)

Comment 4 Jesse Barnes 2015-07-29 15:04:48 UTC 
Looks like module re-load is hanging on BYT?  The test can timeout, but we'll have to reboot to get the system into a usable state.  So I guess there are two bugs here: reload doesn't work on BYT and the reload test needs a timeout and return value.

Here is the dmesg file log with the kmsg tags.

Per CI module reload works on BYT in general. Closing. Please reopen if the problem persists with latest kernels.
