Here's a log on a t3 instance with you patch plus some printk's of mine
showing the EFI memory reserves and with memblock debug.
This crash is NOT explained by the missing pfn_valid() I mentioned in my
earlier email. I don't know if there could be a zone issue here, it does
look like every page we are trying to free is contained in a e820 "usable"
range here unless I really misread something.
Just in case I accidentally screwed up something last week, I will run
a bunch of tests with both my original and your patch + the missing
pfn_valid(), see if that trips anything.
I will separately look at adding the EFI regions to the memblock.memory,
as I think the very first crash I reported smelled a lot like an unmapped
piece of mem_map.
Cheers,
Ben.
