This looks to me as if it is trying to open the SD card (but there
is no SD card in the slot). Why would it do this?
IIRC, the internal storage may actually be connected via SDHCI. I think
this is the case on some tablet hardware.
This is all upstream kernel stuff that we don't really touch
downstream, AFAIK, so you're probably going to get more luck reporting
it to a relevant upstream list or bug tracker, I'd say...
