And error repeats sporadically. After few errors kernel lower SATA link rate to 3.0 and after few more errors to 1.5.

===== increasing SATA link speed =====
After multiple reboots (without power off) ''ata2'' port works in 3.0 instead of 6.0:
kernel: ata3: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
kernel: ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
It looks like SATA link speed is limited by HDD after previous failures.
To restore 6.0 link speed download [[https://github.com/Seagate/openSeaChest/releases|openSeaChest]]:
wget https://github.com/Seagate/openSeaChest/releases/download/test-ci_linux_tar_ownership/openseachest_24.10.15-dev_amd64.deb
