Dear Mr. David, Mr. Christian, First of all, thanks for your replies! David, I will try the same software versions on x86 to see if I am able to replicate the problem on x86, but I suspect it is ARM specific... I'll report back when I have more details. Christian, I'll collect the data you've referred and will disable the power management. Regarding the mesa master version, I've tried it, and the problem just gets worse. With latest mesa, It easily locks up in lightdm login screen, or when navigating through the Ubuntu Mate menus, or with Kodi. I've tested with mesa commit "radv: Implement binning on GFX9" - 6a36bfc64d2096aa338958c4605f5fc6372c07b8. Just one question... when you refer to API traces, you're suggesting to strace kodi, or what do you mean?
