The problem can occur with any application as stated by Boris Ostrovsky ------------ "This can be easily triggered by Linux' page-types (tools/vm/page-types.c) after save/restore.
All it does is it walks the page tables (in fs/proc/task_mmu.c) and eventually trips on bad page. For example: # /page-types -p 2273 -L> /tmp/new [ 2634.501440] pfn 0x159f75 highest_memmap_pfn=0x3ffff [ 2634.502345] BUG: Bad page map in process page-types pte:159f75420 pmd:3178a067 " Which means that any application should be able to trigger this depending on whether 'mprotect' was doing its stuff and migration happend.
