All SMART attributes that would indicate electromechanical failure are at zero raw values. I've also just verified that the 'clunk sound' is a head load cycle. By copying a certain file I can trigger the error and if I check the SMART attributes before and after, I see the 'Load Cycle Count (ID #193)' increased by 2. Currently it is at 1823. Unfortunately, I'm not skilled enough to quickly test with a vanilla kernel on the same OS. Would it be useful if I'd tested using Raspbian Jessie with 4.1 kernel instead? I can exchange the SD card with the OS while keeping everything else the same. The stackexchange post is indeed mine and I have not posted this to the linux-ext4 mailing list. Should I do so? I apologize if I'm doing things out of order here, I have little experience in official linux bug reporting. Attaching dmesg ans syslog files. -- You are receiving this mail because: You are watching the assignee of the bug.
