Fixed by https://patchwork.freedesktop.org/patch/296564/
Comment 3 Lakshmi 2019-05-14 06:41:44 UTC
This issue happened only once drmtip_275 (1 week, 2 days old) on fi-icl-u2 where the BIOS was older version 3121.
Currently this machine is updated with newer Bios atm i.e 3175.
Comment 4 Martin Peres 2019-05-16 12:23:11 UTC
Maarten, could you please land the patch since it has been 10 days and you already got an ack from Simon?

From a customer PoV, the impact is minimal because this is a test issue and the failure happened once. The result is a crash when receiving the signal SIGFPE 
 (invalid floating point operation): see https://support.sas.com/documentation/onlinedoc/sasc/doc700/html/lr1/zid-3511.htm.

The test will be fixed by Maarten's patch. Keeping the priority to medium until the patch lands.
Comment 5 Maarten Lankhorst 2019-05-16 13:02:02 UTC
Should be fixed now.
