Two days ago, I was able to install and get FreeNas 9.3 running on my machine (specs below). After getting it set up, I shut it down until I could work on it some more. Now, it won't start up and is always stuck at the following backtrace in KDB (abbreviated output since I have to type it by hand):
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x0
fault code = supervisor write data, page not present
instruction pointer = 0x20
stack pointer = 0x28
frame pointer = 0x28
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags = resume, IOPL = 0
current process = 0 ()

What I've tried so far:
- Tons of searches for similar issues. I'm only finding stuff that has been resolved since around version 8.0.3
- Reinstalled FreeNAS. Was getting trap 12 during this (same as above backtrace), but got past it somehow.
- Updated motherboard BIOS
Other weird bits of information:
- KDB is showing "real memory = 9663676416 (9216 MB)". I feel like this might be relevant since FreeNAS may be attempting to access memory that isn't there (a full GB extra), in the kmem_alloc() call.
