While with 5.15.2 + patch there weren't errors from libata, with vanilla 5.15.5 (in which patch 'libata: core: add missing ata_identify_page_supported() calls' was included) there are 2 other (new because it wasn't the case with 5.15.4) error messages: sd 5:0:0:0: [sda] Asking for cache data failed sd 5:0:0:0: [sda] Assuming drive cache: write through With the old warning (twice): ata6.00: ATA Identify Device Log not supported To summarize errors: pre-5.15 kernels: no errors from libata. 5.15 - 5.15.4 (twice): Read log page 0x08 failed, Emask 0x1 5.15.5: Asking for cache data failed; Assuming drive cache: write through Same hardware, just upgraded kernel to 5.15.5. I still think that my HDD doesn't deserve error messages in dmesg. Errors from the storage subsystem can be scary for someone.
