Vijayakannanx do you reproduce this issue with latest kernel? If so, please provide the /sys/class/drm/card0/error log
Timeout. Closing this issue due to lack of log. If it occurs again, first re-test with latest kernel and Mesa version since there were improvements pushed in kernel and Mesa that will benefit to your system, and then, if this is still occurring, reopen with attaching gpu crash dump & kernel log.
