med_power_with_dipm causes my T450 to freeze with a SAMSUNG
MZ7TD256HAFV-000L9 SSD (firmware DXT02L5Q).
Switching the LPM to max_performance fixes this issue.

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?

Yes, if it still happens with the latest firmware then blacklisting
it completely is the right thing to do.
Unfortunately for reasons which I do not understand OEM SSDs often use
different (customized?) firmware compared to the model on which they
are based and often see less updates and seem to have more bugs :|

I've just got another freeze with the latest firmware while I was
watching some YouTube videos. I think it's safe to assume this drive
is borked and won't get better, I'll send another patch.
Thanks,
Diego
