Mika, anything to update?
Comment 16 Mika Kahola 2018-07-03 12:42:06 UTC 
Not really. These crc !mismatch errors occurs on multiple tests. I had an kernel patch that I tried but on shard runs another kms_* test was failing so no breakthrough yet, I'm afraid.

There is somethign fishy going on while we read out pipe crc's. I just haven't figured out that yet.
