There was no reset performed. If there was a reset, you would have seen something like: [ 1.441326] ata8: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 1.541250] ata8.00: configured for UDMA/133 [ 1.541411] ata8: hard resetting link Could you please try this patch and see if it improves things for you: https://lore.kernel.org/linux-ide/20230913150443.1200790-1-nks@xxxxxxxxxxx/T/#u Kind regards, Niklas
