Title: incorrect value of /sys/power/image_size
Post by: lanig on 2024/07/13, 14:31:19

Hi all,
After installation of a new kernel, /sys/power/image_size was set to 2452201472 for a swap size of about 30 G but divided in two separated partitions.
This value makes hibernate to fail because there is not enough empty space to create the image though free was saying that most of the swap was available.

Code Select


juil. 06 14:23:17 logodenn kernel: PM: hibernation: Preallocating image memory
juil. 06 14:23:17 logodenn kernel: PM: hibernation: Creating image:
juil. 06 14:23:17 logodenn kernel: PM: hibernation: Error -12 creating image

Setting /sys/power/image_size to 0 makes hibernation possible again.
So, how is computed the value for /sys/power/image_size?

I have just tested it and it also survives a boot process. 8)
