Looking further at the oops, isn't it crashing at saveable+0x27/0x63 ?
Which appears to be snapshot.c / line 184 - BUG_ON(PageReserved(page) &&
PageNosave(page));
I won't claim to understand the patch, but the comments say "Mark memory
gaps and the reserved regions as nosave", which would imply the above
code could be true?
