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
