I don't see anything new that helps. Again, the driver looks like it's operating properly - just reporting the error that it gets. All I can think of is that the requested LBA is out of range, but if that were that case you should be getting a different error (ASC of 21 instead of 20). And one other thing I see is that the debug output from MPR only shows errors for da20:mpr0:0:24:0. The errors at the beginning of the log show several drives, so I'm not sure what to make of that. Are you using the same disks for FreeBSD as you are for Linux? If not, maybe you can do that and see what happens.
