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.

Thank you for the patch, have you updated the firmware and
confirmed that this happens with the latest firmware version too ?
If not please send a new version limiting the blacklist to your
firmware version.

No, I haven't tired the latest one yet.
The last time I saw, Samsung/Lenovo doesn't make it very easy for
Linux users, and I don't have a Windows installation to perform the
upgrade.
