EDITAR 08-07-17 Trataré de reformular la pregunta. ¿Cómo puede aparecer un dispositivo en una 'sesión en vivo' y desaparecer por completo durante un arranque normal?
Frustrarse aquí. En su mayoría, instalación sin problemas 16.04LTS, lo único que no funcionará es el lector de tarjetas MicroSD.
El lector aparece en lspci (00: 12.0 SD Host controller: Intel Corporation Device 2296 (rev 35))

00:1f.3 SMBus: Intel Corporation Device 2292 (rev 35)
02:00.0 Network controller: Intel Corporation Wireless 7260 (rev 83)
La tarjeta aparece si está conectada por un lector de tarjetas USB en tres formatos diferentes, exFat, NTFS y ext3 / ext4.
La tarjeta en el lector interno funcionaba en Windows 10 (exFat).
¡Ahora es frustrante, la tarjeta en el lector interno aparece usando el USB en vivo de Ubuntu (mmcblk2)!
ubuntu@ubuntu:~$ lsblk

└─mmcblk0p1 179:1 0 512M 0 part
Pero con un arranque normal, la inserción de la tarjeta no genera reacción alguna, ni dmesg, ni montaje, ni lsblk, ni nuttin.
Otro elemento de interés, en los 'discos', el 32GIG eMMC integrado en la máquina se muestra como una tarjeta SD. ¿Es posible que Ubuntu no pueda manejar dos controladores SD al mismo tiempo?
Su conocimiento, experiencia y asistencia son apreciados.

La diferencia es establecer las banderas. El arranque de sesión en vivo que funciona tiene los indicadores 'maestro de bus' y 'latencia 0' establecidos. ¿Alguna idea sobre cómo configurarlos durante un arranque normal?
Editar 08-09-17 Un momento ah-ha podría haber sucedido
En un arranque normal que no ve la tarjeta microSD
dana@Astrolaptop3:~$ sudo modinfo sdhci_pci
filename: /lib/modules/4.10.0-30-generic/kernel/drivers/mmc/host/sdhci-pci.ko
y desde un arranque de sesión en vivo que ve la tarjeta microSD
ubuntu@ubuntu:~$ sudo modinfo sdhci_pci
filename: /lib/modules/4.8.0-36-generic/kernel/drivers/mmc/host/sdhci-pci.ko
Entonces, el controlador que funciona es parte del núcleo 4.8.0-36, el controlador que no funciona es parte del núcleo 4.10.0-30. ¿Cómo hago para usar el controlador anterior que funciona? No necesariamente quiero revertir todo el kernel, solo el controlador.

lspci -nnk | grep -A3 'SD Host controller'? Además, ¿podría enchufar una tarjeta en el lector de tarjetas (previamente vacío), esperar ~ 30 segundos, luego ejecutarsudo dmesg | tail -n 100e incluir también la salida en su pregunta? Gracias.Respuestas:
Volviendo al kernel 4.8.17-040817-generic soluciona el problema. Ahora funciona.
4.8 tiene las banderas 'Bus Master' y 'latencia 0' establecidas y no puedo entender cómo configurarlas de otra manera. 4.10.xy 4.12.x se probaron, ambos rotos.
No es una buena respuesta, pero es una respuesta. La siguiente pregunta es ¿por qué se rompe 4.10.xxx?
EDITAR 08-12-17
Algo esperado: revertir Kernel a 4.8 rompió el sistema. Me rindo. Otro en la lista de cosas que no funcionan en Ubuntu. Pero al menos tengo más práctica limpiando el disco y comenzando de nuevo.

Tuve el mismo problema con el mismo controlador de host SD (8086: 2296) en un Intel NUC5CPYH usando mi propia compilación de kernel 4.14.69. Aparentemente en ese kernel (¿y posiblemente también en su kernel Ubuntu 4.10.x?) Aunque sdhci-pci parece estar funcionando, MMC no se inicializa a menos que el controlador pinctrl relevante (pinctrl-cherryview en mi caso) se cargue primero.
