I had a very similar problem with a RAID1 on a raid hardware controller. I 
managed to re-build the broken array from within the controller's BIOS 
during bootup.

It seems this error comes from the broken DMA support on 5.3, so I disabled 
DMA for my disks on this server via sysctl.

Hey guys, what's the status of this DMA issue?

Greetings, Matthias
