Description
I have gotten the following diagnostic from the MMC/SDHC driver package. The driver in the previous kernel I have been using for some time, Linux 3.10.34, worked correctly.

Replying to anonymous:
Could you try older openwrt revisions with kernel 4.1, 3.18 and so on and report what kernel version cause this problem?
I'll try as time permits. My standard kernel has been 3.10.34 for some time, which does work.

How does one find out what 'git' incantation to pull a specific kernel for a given target, or find out what kernels had patches for specific kernels?
I'm using the mpc85xx target.

Damn didn't fill in the email field...
In any case, there is a 15.05 release for OpenWRT which seems to have a 3.18 set of patches.
I'll try that tomorrow if I can.

IMHO related is ticket #21995

That ticket doesn't seem to have my symptoms. Which is a number of reads with a long timeout.
I'm now looking at kernels 3.10.xxx and seeing how I can compile them in 'external' mode relative to my working OpenWRT hierarchy.
Could you try older openwrt revisions with kernel 4.1, 3.18 and so on and report what kernel version cause this problem?
