The swiotlb messages have been introduced by this upstream commits,
which has been backported in various stable branches:
commit 8396c793ffdf28bb8aee7cfe0891080f8cab7890
Author: Sam Protsenko <semen.protsenko@linaro.org>

mmc: dw_mmc: Fix IDMAC operation with pages bigger than 4K
You can try to build a kernel with it reverted to see if it also fixes
the corruption issue.
In the meantime, I am working on a patch.
