Bug#803899: linux-image-4.2.0-1-amd64: Intel NUC built-in SD card reader requires PINCTRL module support
Package: src:linux
Version: 4.2.5-1
Severity: normal
Dear Maintainer,
(Resending bug report because the Debian BTS appears to
have dropped my previous message from another account.
Sorry if this is a dupe.)
The built-in SDHC card reader on my Intel 5th Generation
Braswell NUC (NUC5PPYH) doesn't work under Debian Unstable
running Linux kernel 4.2. The card reader, however, works
fine under an Ubuntu 15.10 live USB session, which runs
a differently configured Linux 4.2 kernel.
Below is a comparison between the runtime kernel
messages and kernel configuration for both Debian Unstable
and Ubuntu 15.10 (Wily Werewolf).
The important difference between the Debian and Ubuntu
kernels with regard my problem is the enabling of several
PINCTRL options in the Ubuntu kernel config.
Comparison between the relevant parts of dmesg output for
Debian Unstable and Ubuntu Wily Werewolf (15.10):
