--- Comment #2 from Lukas <dse.ssd@...il.com> ---

I was suspecting hardware problems initially, but now I don't think that's the
case - both short and long SMART self-tests as well as vendor diagnostic tests
(including a 10 hour scan of every sector) produced no errors. 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.
