Hi Hans and Jens,

I just wanted to give you guys an update about this problem.

I've managed to update my SSD firmware to the latest version[1].

For running the update, I've had to install Windows 10, ran the
firmware update, remove Windows and reinstall Arch Linux.

The latest version of the firmware is DXT04L5Q, and it looks like
there hasn't been a new update since 2015.

I'll be running with med_power_with_dipm and hope this firmware update
fixes the problem, if it doesn't and I get another freeze, I'll send
another patch blacklisting the drive completely. Is that OK?
