I set a dump device in rc.conf but when the machine paniced I got this: Fatal trap 12: page fault while in kernel mode fault virtual address = 0x14 fault code = supervisor write, page not present instruction pointer = 0x8:0xc0166429 stack pointer = 0x10:0xd60359cc frame pointer = 0x10:0xd6035a00 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 27 (syncer) trap number = 12 panic: page fault syncing disks, buffers remaining...

This was followed by a normal bootup and then: savecore: no dumps found As I've said, I am using vinum to mirror my swap. However, I set dumpdev to point to one half of the mirror directly. My reasoning for this was that if vinum had died the kernel wouldn't be able to dump to a vinum controlled device. Any thoughts on how I can procede?
