Bug#855911: linux-image-4.9.0-1-armmp: MMC failure on A20-OLinuXIno-LIME2
Package: linux-image-4.9.0-1-armmp
Severity: normal
I recently switched to linux 4.9.0 (jessie-backport package on one, package
from testing in the other) and latest u-boot on my two A20-OLinuXIno-LIME2
boards, which were running seriously outdated versions of linux until now (4.4
and 4.0).
Both systems have their rootfs on a microSD card, and have had the same issue
after the upgrade: within hours of the boot process, the µSD fails to
read/write with various errors from the mmc subsystem. In one of the systems (I
don't have physical access to the second sytem right now), I have successfully
reverted to linux 4.4, so this isn't a hardware issue or an issue caused by
u-boot.
Although it isn't about the same hardware nor the same version of the kernel,
there is a similar bug report on Fedora's bugtracker, suggesting this is an
upstream problem in the sunxi-mmc driver, but I haven't tried upstream's kernel
without Debian patches yet, nor have I attempted to bisect the issue:
https://bugzilla.redhat.com/show_bug.cgi?id=1419575
Here is a log from one of the two systems (the one that uses the kernel from
testing):
