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.
