Description Maarten Lankhorst 2018-07-05 08:41:18 UTC
A lot of tests on fi-byt-squawks fail with a CRC mismatch. Manual verification doesn't show any major visual glitches, and retrieving a crc multiple times may give different values.

PSR, DRRS and FBC are all disabled on that machine, so it must be something else.
No FIFO underruns show up either.

Can you point to one of the CI failures for reference?
Comment 3 Lakshmi 2018-09-11 07:03:52 UTC
Rising the priority to high as issue occurs in every round with BAT tests.
