Thanks, I'm afraid that patch gives me a BUG at snapshot.c:184 during suspend. However, with more testing, I've found that my resume problem only occurs with CONFIG_HIGHMEM64G (the default in a Fedora installation). I've got images of the screen dumps for both (from one of a few times that it didn't reboot during resume), and can post them if they'd be any use? The resume error is "unable to handle kernel paging request", EIP is at copy_loop+0xe/0x15.
