For reference, I am running 6.0.0, with the following two patches applied
on top:

ARM/dma-mappіng: don't override ->dma_coherent when set from a bus notifier
ARM/dma-mapping: remove the dma_coherent member of struct dev_archdata

Turris Omnia (Armada 385), EXT4 rootfs on a Kingston UV500 mSATA drive.

I have 16 days uptime and am error-free, as far as I can tell. Definitely,
not a single EXT4-fs error.

Regards, Klaus
