11 Doh! I didn't have CONFIG_USB_XHCI_HCD enabled.
13 The kernel is now finding the root partition based on the DOS
14 paritition table verison of the PARTUUID. Yay!
16 I'm a bit surprised that xhci support isn't enable by default these
17 days. It's been yonks since you could buy a new machine that didn't
18 have an xhci controller, and presumably having support enabled on an
19 old machine doesn't cause problems.
21 The Intel wireless interface isn't showing up yet, because the
22 firmware loading is failing. It worked when booting from the minimal
23 install image, so I've still got some kernel configuration tweaking to
24 do. I have vague memories of the iwlwifi driver not working well when
25 compiled as part of the kernel but working better as a module...
