Thanks. > http://www.dresco.co.uk/debug/resume_from_disk.jpg This one indicates that page tables are corrupted in the restore loop, just like it used to happen on x86_64 some time ago. Can you confirm that it doesn't happen if HIGHMEM64 is not set? > http://www.dresco.co.uk/debug/suspend_e820_patch.jpg This one is really strange, like a miscompilation or something. Could you identify which line of code corresponds to count_data_pages+0x38 (using gdb)? Rafael -- You never change things by fighting the existing reality. R.
