@Sujaritha, Can you please add your assessment and set the severity of this bug.
Bug Assessment : • Seen three times on TGL (Once in CI, twice on TryBot runs). • pm_rpm@module-reload is basic subtest of pm_rpm to check driver unload/reload with and without the display. • In this case, after the test starts the machine tries to reload but just hangs. Not much data available to pin point the exact reason. Similar bug seen couple of months back on SKL due to dpll issue. • Will continue to track and see if the bug is hit again in CI. Setting to normal for now.
Issue not seen for more than two months now.
