Re: [LinuxBIOS] DK8-HTX Early Hang with HTX Card Intsalled

[Lu, Yinghai]

For MTRR error, I think the kernel is not happy with the uncachable
entry for the memory hole.

Try to install only 2G to see if the problem will go away.

Then we can 
1. modify the kernel to make it like mtrr layout for setting.
2. or change mtrr to increase style..., if the kernel is too ..

Yep, that's the ticket.  All remaining is the message:
  PCI: No IRQ known for interrupt pin C of device 0000:40:01.0. Probably
  buggy MP table.
which seems plausibly ignorable since it seems to actually be
getting interrupts.

sh-3.1# cat /proc/mtrr
reg00: base=0x00000000 (   0MB), size=2048MB: write-back, count=1
reg01: base=0xfd500000 (4053MB), size=   1MB: write-combining, count=1

fd400000-fd5fffff : 0000:40:01.0
  fd400000-fd5fffff : ib_ipath

Given that, how do you want to go forward?  I've got compute
nodes with nothing but the HTX installed and storage nodes with
HTX and a couple PCI-X 3ware cards, so only two cases for me
admits hardcoding hacks.  Of course, it would be nice to solve
the problem in general and call the DK8-HTX 'working' and I'm
happy to spend effort to get there rather than the hack.  :)
