> > Attached the config. It just happens on boot. Hi Sasha, I have tried unsuccessfully to reproduce the bug in qemu with 20G RAM, and 8 CPUs. Patch "mm: uninitialized struct page poisoning sanity" should be improved to make dump_page() to detect poisoned struct page, and simply print hex in such case. I will send an updated patch later. How do you run this on Microsoft hypervisor? Do I need Windows 10 for that? BTW, I am going to be on vacation for the next two week (going to Israel), so I may not be able to response quickly. Thank you, Pasha
