Bug#912298: linux-image-amd64: SD card reader on Dell E7250 doesn't work in Debian Stretch
Package: linux-image-amd64
Version: 4.9+80+deb9u6
Severity: normal
There is a known issue on 4.x kernels for this device:
01:00.0 SD Host controller: O2 Micro, Inc. SD/MMC Card Reader Controller
(rev 01)
sdhci-pci 0000:01:00.0: SDHCI controller found [1217:8520] (rev 1)
Whenever we try to use this reader with any kind of SD card, it doesn't
work
and reports the following in dmesg:
[ 4357.435988] sdhci: Timeout waiting for Buffer Read Ready interrupt
during tuning procedure, falling back to fixed sampling clock
[ 4357.443304] mmc0: tuning execution failed: -5
[ 4357.443315] mmc0: error -5 whilst initialising SD card
There is a same issue open on Ubuntu bug tracker:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1514821
I have tried the solution from:
https://www.0xf8.org/2016/01/workaround-for-broken-o2-micro-sd-card-reader-support-since-linux-kernel-version-4-1-8/
which proposes loading the `sdhci` module with a debug_quirks2="0x4"
flag, but it doesn't work and people report this error comes back after
every kernel update.
This bug persisted since Debian Stretch appeared and never been fixed in
any of kernel updates.
