Comment 3 Arek Hiler 2019-04-25 06:36:47 UTC
This is quite likely test's fault. When the DP receiver on the chamelium side needs its Finite State Machine handling due to mode/configuration changes it signals that to us by sending hot-plug events. Then we need to do DPMS cycle.

Current implementations spawns a thread monitoring for those events, but that seems to be prone to race conditions, and if we make XMLRPC call to chamelium before it is done we can get this error.

We have to re-implement FSM handling at the call site, so whenever we get this error we force the handling (or wait till the handling is done).

I have seen similar behavior on my local SKL too.

Comment 5 James Ausmus 2019-06-06 18:32:09 UTC
Hasn't been seen on ICL in 285 runs. Removing ICL from the affected platform list.

CML hasn't seen this in 123 runs, will keep this open for CML to monitor for re-occurence
