Did this diff ever show up somewhere? Getting the network running would make
further kernel tests on Skylake hardware much easier. Currently I'm using
a FAT partition to exchange data.

I acquired an Asus G20CB with i7-6700 last week and managed to install a
recent NetBSD kernel. Here is the dmesg output:

Errors and unsupported devices:

ACPI Exception: AE_NOT_FOUND, During name lookup/catalog (20150717/psobject-237)

Maybe not NetBSD's fault. I have read on the ASUS forum that Linux has the
same problem and the ACPI tables might be corrupt. Can this cause any
trouble?

2. ACPI Exception: AE_NOT_FOUND, While evaluating Sleep State [\_S1_] (20150717/hwxface-646)
ACPI Exception: AE_NOT_FOUND, While evaluating Sleep State [\_S2_] (20150717/hwxface-646)

A side effect of the first problem? Probably not important either.

3. acpifan0..4 is detected and attached, but doesn't work. envstat(8)
shows an error for these fans.

4. vga0 at pci1 dev 0 function 0: vendor 10de product 13c2 (rev. 0xa1)
The NVIDIA GTX 970. Nouveau does not yet support the Maxwell family of GPUs.
I could probably switch to the onchip intel HD530 graphics...?

5. vendor 8086 product a12f (USB serial bus, xHCI, revision 0x31) at pci0 dev 20 function 0 not configured
That's the Skylake xHCI USB 3.0. Our xhci driver is still very experimental.
It may detect some devices, but most of the time it hangs.

6. vendor 8086 product a13a (miscellaneous communications, revision 0x31) at pci0 dev 22 function 0 not configured
The MEI (Management Engine Interface). Not really needed.

7.vendor 1b21 product 1242 (USB serial bus, xHCI) at pci2 dev 0 function 0 not configured
This is the ASMedia USB 3.1 interface. Booting a kernel with xhci enabled
will freeze the system, as it is completely unsupported. For the moment
I would suggest the following patch:

8. vendor 10ec product 8821 (miscellaneous network) at pci3 dev 0 function 0 not configured
Realtek 8821AE WLAN (b/g/n/ac). Ok, personally I don't care very much, as
this is a desktop and not a laptop computer.

9. vendor 8086 product a121 (miscellaneous memory, revision 0x31) at pci0 dev 31 function 2 not configured
This is the Power Management Controller. Might be useful?

10. vendor 8086 product 15b8 (ethernet network, revision 0x31) at pci0 dev 31 function 6 not configured
And finally the Gigabit Ethernet NIC. Would be nice to get it running for
a start. :)
