hantro: Corrupted buffers
I can't trigger it reliably but sometimes hantro just spits out corrupted buffers so the video output is mostly garbage (with bits from actual frames though). It might be related to power saving (i can sometimes trigger it when blanking the display). Unloading the hantro/v4l modules or restarting the compositor doesn't unbreak this so a reboot is required.
Mostly filing this so we have a bug to gather more information.
