Hello,
I’m using kernel 6.1.60-1 LTS , and after the last update I gave a shoot on kernel 6.6.0-1. When I switched to this new kernel, some of my SATA disks stopped working. Looking at dmesg I can see messages like this all the time:
[68055.848769] ata3: found unknown device (class 0)
[68080.059997] ata3: softreset failed (1st FIS failed)
[68080.060004] ata3: limiting SATA link speed to 3.0 Gbps

[68105.452514] ata3: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[68105.452518] ata3: link online but 1 devices misclassified, retrying
[68111.242550] ata3: link is slow to respond, please be patient (ready=0)
[68116.235930] ata3: found unknown device (class 0)
This goes on forever. df shows disks normally, but IO just don’t work and any data is inaccessible.
Note that all my disks are ext4, so there is nothing to do with zfs deprecation on the latest update.
Then I switched back to old LTS kernel, and everything is working seamless again, no weird message on dmesg. I believe this to be an important regression on kernel 6.6. I tried to search a bit on kernel changelog or issue tracker, found similar but older issues. I was unable to find anything more recent than 6.1.
Thank you.
