I'm glad it's getting better. Your e820 doesn't look right, though.
[ 0.000000] BIOS-provided physical RAM map:
[ 0.000000] BIOS-e820: 0000000000000000 - 000000000009f400 (usable)

Your devices have resources mapped from c0000000-e0000000 that don't show
up. I can't remember where it would get that value from, but I think it is
worth looking into.
Thanks,
Myles
