Will you please try to add the boot option of "i915.enable_ppgtt = 0" and see whether it is helpful? Thanks

I added the option, however i915 driver seems to not recognize it, please see below: dmesg | grep i915 [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-3.13.0-74-generic root=UUID=9bb8b128-9495-4667-9cda-1048bd45abd9 ro quiet splash i915.enable_ppgtt=0 vt.handoff=7 [ 0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-3.13.0-74-generic root=UUID=9bb8b128-9495-4667-9cda-1048bd45abd9 ro quiet splash i915.enable_ppgtt=0 vt.handoff=7 [ 0.949725] i915: unknown parameter 'enable_ppgtt' ignored [ 1.228717] i915 0000:00:02.0: irq 42 for MSI/MSI-X [ 2.312179] i915 0000:00:02.0: fb0: inteldrmfb frame buffer device [ 2.312181] i915 0000:00:02.0: registered panic notifier [ 2.325629] [drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0 What is the purpose of enable_ppgtt flag? Do I need to upgrade to different i915 version? Thanks
Your Linux kernel is too old. It would be better to try the latest kernel first.
Hello ykzhao, I managed to update the kernel. Please see below: uname -r 4.4.0-21-generic dmesg | grep i915 [ 0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-4.4.0-21-generic root=UUID=9bb8b128-9495-4667-9cda-1048bd45abd9 ro quiet splash i915.enable_ppgtt=0 vt.handoff=7 [ 0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.4.0-21-generic root=UUID=9bb8b128-9495-4667-9cda-1048bd45abd9 ro quiet splash i915.enable_ppgtt=0 vt.handoff=7 Can you please advise if the option you mentioned is active? What are the next steps. Thank you
Now the ppgtt option is recognized on the new kernel. Will you please use the kodi to play the same video and see whether the GPU hang is still triggered? Thanks Yakui
The bug will be closed as there is no response for more than six months. If the issue still is reproduced, please file a new bug or reopen it. Thanks Yakui
