Now to all of the forum
Thanks we are going to try this.
Can you explain why this can cause this issue - is the NVDIMM memory space
also being randomized?
Is it done during runtime?
Yes, kaslr randomizes the direct map. We have seen problems with it in
the past relative to setting up pmem mappings. We fixed one such bug
with this commit:
fc5f9d5f151c x86/mm: Fix boot crash caused by incorrect loop count
calculation in sync_global_pgds()
...but it appears we may have another bug in this area.
