Subject: Re: [PATCH 1/1] drm/amdgpu: Fix TLB flush failures after hibernation resume

Hi Mario,

Thanks for the additional context about /sys/power/image_size and the
GitLab issue reference.

My platform configuration appears to be well set up for hibernation:

  - 30 GB RAM / 30 GB swap available
  - /sys/power/image_size: ~12 GB (13033648128 bytes)
  - Not using secure boot
  - Swap partition is adequately sized for VRAM eviction

Based on the GitLab discussion you referenced, my image_size should be
sufficient. So the known hibernation limitations shouldn't be blocking
factors on my system - the TLB flush failure appears to be the main
remaining issue.

I'll capture stack traces as Alex requested and follow up with the
debugging information in the next few days.

Thanks,
Ionut
