 It's not clear to me whether this is just because the dump is bad or
 because savecore is still broken, but when I tried to run savecore
 after the last panic (unless I have mixed up panics in my memory,
 which is entirely possible at this hour), it started off by saying
 
 savecore: kvm_read: invalid translation (invalid level 3 PDE)
 
 but proceeded to start writing a core dump to disk.  In the morning
 (it's a 32 GB dump being written to a sync ffs) I'll see whether gdb
 finds this core dump digestible.
