On this machine the admincd (admincd-amd64-20130620.iso) fails to find any USB device and thus boot can't succeed. Running dmesg from shell shows no reasonable USB handling. # lspci -k 00:00.0 Host bridge: Advanced Micro Devices, Inc.

Possible corroboration. Autobuild installers since around April 2015 are missing xhci_pci, even though xhci_hcd can't operate without it. --- BEGIN xzcat gentoo.igz | cpio --list -v --- drwxr-xr-x 2 root root 0 May 21 06:28 lib/modules/3.18.12-gentoo/kernel/drivers/usb/host -rw-r--r-- 1 root root 135267 May 21 06:28 lib/modules/3.18.12-gentoo/kernel/drivers/usb/host/xhci-hcd.ko -rw-r--r-- 1 root root 36631 May 21 06:28 lib/modules/3.18.12-gentoo/kernel/drivers/usb/host/uhci-hcd.ko -rw-r--r-- 1 root root 34288 May 21 06:28 lib/modules/3.18.12-gentoo/kernel/drivers/usb/host/ohci-hcd.ko -rw-r--r-- 1 root root 19529 May 21 06:28 lib/modules/3.18.12-gentoo/kernel/drivers/usb/host/sl811-hcd.ko drwxr-xr-x 2 root root 0 May 21 06:28 lib/modules/3.18.12-gentoo/kernel/drivers/pcmcia --- END xzcat gentoo.igz | cpio --list -v --- --- BEGIN scripts/extract-ikconfig gentoo --- # USB Host Controller Drivers # # CONFIG_USB_C67X00_HCD is not set CONFIG_USB_XHCI_HCD=m CONFIG_USB_XHCI_PCI=m CONFIG_USB_EHCI_HCD=y CONFIG_USB_EHCI_ROOT_HUB_TT=y CONFIG_USB_EHCI_TT_NEWSCHED=y CONFIG_USB_EHCI_PCI=y # CONFIG_USB_EHCI_HCD_PLATFORM is not set # CONFIG_USB_OXU210HP_HCD is not set CONFIG_USB_ISP116X_HCD=m # CONFIG_USB_ISP1760_HCD is not set # CONFIG_USB_ISP1362_HCD is not set # CONFIG_USB_FUSBH200_HCD is not set # CONFIG_USB_FOTG210_HCD is not set CONFIG_USB_OHCI_HCD=m CONFIG_USB_OHCI_HCD_PCI=m # CONFIG_USB_OHCI_HCD_SSB is not set # CONFIG_USB_OHCI_HCD_PLATFORM is not set CONFIG_USB_UHCI_HCD=m CONFIG_USB_U132_HCD=m CONFIG_USB_SL811_HCD=m # CONFIG_USB_SL811_HCD_ISO is not set CONFIG_USB_SL811_CS=m CONFIG_USB_R8A66597_HCD=m # CONFIG_USB_HCD_BCMA is not set # CONFIG_USB_HCD_SSB is not set # CONFIG_USB_HCD_TEST_MODE is not set --- END scripts/extract-ikconfig gentoo --- Virtually certain that: - xhci-pci.ko - ohci-pci.ko are supposed to be on the initrd but are missing
(In reply to lkd-gentoo from comment #1) (sorry, hit enter early) Pretty sure the result is: if the system is booted from a USB device, it can't find image.squashfs properly once the initrd has started running.
I'm fairly confident that this was fixed a good while ago but please re-open if you are still experiencing this problem
