c3700 boot failure (protection ID trap)

[Bjorn Helgaas <bhelgaas@xxxxxxxxxx>]

I'm trying to test some PCI changes on a c3700, but recent kernels
don't seem to work at all.  74ea15d909b311 (current upstream) and v3.2
both fail as shown below.  I'm using c3000_defconfig (attached for
74ea15d909b311).  Should I expect this to work?

v3.0 gets farther, but then gets into a loop of
__find_get_block_slow() messages like this:

        ...
        md: autorun ...
        md: ... autorun DONE.
        __find_get_block_slow() failed. block=0, b_blocknr=1
        b_state=0x00000020, b_size=4096
        device blocksize: 4096
        __find_get_block_slow() failed. block=0, b_blocknr=1
        ...
