Seems like it came back to life.
Comment 4 Chris Wilson 2017-04-03 09:31:26 UTC
Going by those results, there is no bug. There is an old Baytrail instability bug (w/a max_cstate=0) that can cause a hard hang, so unless this is still occurring across multiple machines (which iirc recent CI is all about byt j1900) or we have something actionable from the logs, max_cstate=0 would be the next step.
Comment 5 Tomi Sarvela 2017-04-03 13:15:40 UTC
Added w/a max_cstate=0 to BYT-j1900 kernel command line.
Comment 6 Tomi Sarvela 2017-04-03 14:00:54 UTC
With the suggestion of Mika Kuoppala, removed max_cstate=0 and added maxcpus=2

maxcpus=2 was chosen as a workaround for pm/intel_idle problems with 4 core baytrails. References:

Assuming that these incompletes were the irq bugs fixed about the same time as these were filed.
