Description Thorsten Leemhuis 2011-08-18 12:35:01 UTC
Description of problem:
config-generic right now defines CONFIG_USB_XHCI_HCD as "m" and dracut doesn't include the resulting module (xhci-hcd) it in the initramfs that is build for Live and install ISOs. 

Hence they won't boot if you transfer the ISOs to a USB flash drive which you then connected to a USB port that is handled by a XHCI controller, as the driver for that controller is unreachable in the initramfs stage -- hence dracut can't find the RootFS and has to give up.

There are two solutions to solve this:
- always build xhci-hcd into the images dracut builds

Setting it to =y seems pretty simple.  The =m setting we have now pre-dates fedora git so it's ancient ;).

I'll see if I can dig up the commit for the =m to make sure I'm not missing something obvious.

Should be fixed in tomorrow's rawhide.
