Comment 2 Jani Saarinen 2017-10-11 11:37:17 UTC 
Are these more Chamelium issues than driver / IGT issues?
Comment 3 Marta Löfstedt 2017-10-16 10:12:50 UTC 
The issue described above has not been reproduced for a very long time. The last 10 times this test has failed it has always been a I2C issue:
	

(chamelium:1337) igt-chamelium-CRITICAL: Test assertion failure function chamelium_rpc, file igt_chamelium.c:302:
(chamelium:1337) igt-chamelium-CRITICAL: Failed assertion: !chamelium->env.fault_occurred
(chamelium:1337) igt-chamelium-CRITICAL: Chamelium RPC call failed: RPC failed at server.  <class 'chameleond.utils.i2c.I2cBusError'>:I2C access error
Subtest dp-crc-fast failed.

However, as discussed in BUG 102672, there appear to be an issue with Chamelium I2C communication.

Also, note linktraining issue in:
https://bugs.freedesktop.org/show_bug.cgi?id=102505
Comment 4 Jani Saarinen 2017-10-16 11:08:29 UTC 
Dropping priority.
