Description Jan Vesely 2019-03-13 19:38:06 UTC

First bad commit:
commit a1378639ab19682a818ee627745db7f67485d406
Author: Marek Olšák <marek.olsak@amd.com>
Date:   Thu Feb 7 00:01:13 2019 -0500

    radeonsi: always use compute rings for clover on CI and newer (v2)
    
    initialize all non-compute context functions to NULL.
    
    v2: fix SI

hangs on carrizo, iceland, raven. The benchmark can be stopped using crtl+c, but the system is unstable after; won't suspend, hangs on reboot.
