Subject: BUG: 1bbbbe7 (x86: Exclude E820_RESERVED regions...) PANIC on boot
Date: Sat, 20 Oct 2012 17:06:29 -0700	[thread overview]
Message-ID: <20121021000629.GA2835@bill-the-cat> (raw)

Hello all,

I grabbed 3.7-rc2 and found the following on boot:
PANIC: early exception 08 rip 246:10 error 81441d7f cr2 0

A git bisect says that this problems came from:
1bbbbe779aabe1f0768c2bf8f8c0a5583679b54a is the first bad commit
commit 1bbbbe779aabe1f0768c2bf8f8c0a5583679b54a
Author: Jacob Shin <jacob.shin@amd.com>

    x86: Exclude E820_RESERVED regions and memory holes above 4 GB from direct mapping.
    
    On systems with very large memory (1 TB in our case), BIOS may report a
    reserved region or a hole in the E820 map, even above the 4 GB range. Exclude
    these from the direct mapping.


The box in question is an Asus motherboard with AMD Phenom(tm) II X6
1100T and 16GB memory.  Happy to provide any other information required.
