Inconsistent memory map preventing hibernation #81

Closed r-vdp closed 1 year ago

r-vdp commented 1 year ago

Hibernation of my StarBook Mk VI (Intel, coreboot) fails because the memory map passed to the kernel seems to be different on every boot. Below are a couple of memory maps that I captured, you can notice a difference for instance in the fourth region, which has a different ending address in all three mappings.

Is there any way to deal with this so that hibernation can be used?

Short answer is no, UPL mentioned in #71 might actually fix it as it avoids the resource allocator script and uses hobs.
