Heya,
On a Cherrytrail device (the MS Surface 3), trying to install to the
internal eMMC, I get write errors with the controller timing out.
I'm using a self built 4.3.0-0.rc4.git3.2.fc24.x86_64.
Any ideas?
Cheers

HC doesn't decrements blk cnt to zero means your data path is blocked.
So I guess it's either a Noc/Qos problem of your chip or "too busy" for
emmc to pragramme the data.

No, sdhci finally complete the tansfer. So, you can try to augment the
timeout [here, mod_timer(&host->timer, timeout)] to see how the things
going.
