Hi,
Did you also make sure that you copy any ata options from your old installation? e.g. For my own Helios64 I have had similar issues and those were resolved by limiting the SATA link speed to 3Gbps:
extraargs=libata.force=1:3.0G,2:3.0G,3:3.0G,4:3.0G  
The internets say that those ATA errors are caused by the the disk not responding to a controller request in time. Mostly it is advised to replace the [S]ATA cables and to make sure contacts are clean and no crosstalk/EMI can occur. A reduction in the ATA link speed also helps, which in my case sure did.
 
Do keep in mind, that if you have regular spinning drives, the most throughput you will get out of your drives will be around 100~140 MB/s, which translates to roughly 1.5 Gb/s. So decreasing the linkspeed will not cause any slowdown, your drive's throughput will remain the performance bottleneck.
 
For my Helios64, I have had some issues with the left-most (or top) disk, as the connectors did not protrude well enough, or had a little too much flex which caused the left-most disk from sometimes not being detected at all. Reseating and pressing on the connector from the rear helped that issue.
 
As the internets mention these errors are the ATA driver complaining about not hearing from the drive(s) in time (or at all), you might want to experiment with a lower CPU frequency, or perhaps not using any of the dynamic freq scaling governors, but sticking to the powersave or performance one.
