That's amazing in itself :) Many of my test machines are able to boot the x86 defconfig bzImage to a shell, so it's more like an "Ingo's minconfig". ;-) /me tries to look innocently but fails miserably > > diff --git a/arch/x86/configs/x86_64_defconfig b/arch/x86/configs/x86_64_defconfig > > index e32fc1f274d8..ac9ae487cfeb 100644 > > --- a/arch/x86/configs/x86_64_defconfig > > +++ b/arch/x86/configs/x86_64_defconfig > > @@ -243,6 +243,7 @@ CONFIG_USB_HIDDEV=y > > CONFIG_USB=y > > CONFIG_USB_ANNOUNCE_NEW_DEVICES=y > > CONFIG_USB_MON=y > > +CONFIG_USB_XHCI_HCD=y > > CONFIG_USB_EHCI_HCD=y > > CONFIG_USB_EHCI_TT_NEWSCHED=y > > CONFIG_USB_OHCI_HCD=y > > You can probably turn ehci and ohci off if you have xhci in the > "default" system now. Also, could we please refresh this in the 32-bit defconfig as well. Other than that the patch looks good to me, no objections to adding convenience options for people who have actually booted the thing on reasonably common PC hardware. Thanks, Ingo
