Well, just a guess, but I'd say your problem is with kernel device
drivers for input. Usually people have the basic text showing up on
their console and the complaints are about how to get ^C and other
tty-specific features to work while using /dev/console. Your problem
sounds more like the Linux virtual console subsystem isn't connecting
to your input devices. I'd suggest poking around in the input drivers
section of the config and make sure things are compiled as "=y" and
not as modules.
Well, in 3 different kernels there were:
CONFIG_INPUT=y
CONFIG_INPUT_MOUSEDEV=y
CONFIG_INPUT_KEYBOARD=y
but only 2 of the 3 work, the third one ignores input. Oddly 3.10.108
was the one originally giving me problems, so rebuilt it using "menu
oldconfig" starting from the config-3.10.0-957.5.1.el7.x86_64 from
Centos 7 and then 3.10.108 worked. But the 3.10.108 kernel had problems
with xfs. So built kernel 3.14.78, starting from the last good 3.10.108
config, and that kernel does not respond (but xfs works!)

This is really frustrating! Perhaps there is some kernel parameter
for 3.10.108 kernels which needs to be set (or unset)??? These are
built into the kernel, seems like they should be enough
CONFIG_HID=y
CONFIG_HID_GENERIC=y
CONFIG_USB_HID=y
CONFIG_USB_SUPPORT=y
CONFIG_USB_COMMON=y
CONFIG_USB=y
It is definitely the kernel. If the custom (based on "make
menuconfig" of boel)
3.10.108 kernel is replaced with a stock Centos 7 kernel then
What do you get from "grep CONSOLE .config" in each of the two
kernels ?
The one where the keyboard does not work:
# CONFIG_NETCONSOLE is not set
CONFIG_VT_CONSOLE=y
CONFIG_HW_CONSOLE=y
# CONFIG_VT_HW_CONSOLE_BINDING is not set
CONFIG_SERIAL_8250_CONSOLE=y
CONFIG_SERIAL_CORE_CONSOLE=y
CONFIG_VGA_CONSOLE=y
CONFIG_DUMMY_CONSOLE=y
The one where where the keyboard does work:
CONFIG_NETCONSOLE=m
CONFIG_NETCONSOLE_DYNAMIC=y
CONFIG_CONSOLE_TRANSLATIONS=y
CONFIG_VT_CONSOLE=y
CONFIG_VT_CONSOLE_SLEEP=y
CONFIG_HW_CONSOLE=y
CONFIG_VT_HW_CONSOLE_BINDING=y
CONFIG_SERIAL_8250_CONSOLE=y
CONFIG_SERIAL_CORE_CONSOLE=y
CONFIG_CONSOLE_POLL=y
# CONFIG_LP_CONSOLE is not set
CONFIG_VIRTIO_CONSOLE=m
CONFIG_VGA_CONSOLE=y

CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY=y
CONFIG_FRAMEBUFFER_CONSOLE_ROTATION=y
CONFIG_USB_SERIAL_CONSOLE=y
# CONFIG_PSTORE_CONSOLE is not set
CONFIG_KGDB_SERIAL_CONSOLE=y
That said, there are a zillion other differences...
