SATA Errors - resetting link, down speed, failed commands

NXP LX2160
1

Hello! I recently acquired a Honeycomb LX2 and got it working fine with Fedora 38. I am currently attempting to hookup 4x SATA SSD to it and create a RAID10; however, as soon as I create the RAID I get many ATA errors and the system locks up. I know the disks are good with less than 5000 hours each and I swapped out the SATA cables for new in box cables, same for the power supply cables to the drives. I happens on all four ports in any configuration:

We have found that the SATA controller on the lx2160a has issues with some SSDs firmware. Generally I have found cables that are 40-50CM’s are the most reliable. Additionally you can try the kernel commandline option libata.force=noncq. Otherwise forcing the controller to SATA2 mode as the default will generally git rid of the errors.

Yes! That kernel option worked perfectly - found it last night and that seems to have solved most of the issues. Thanks a bunch!
