Subject: [PATCH v2] libata: Apply NOLPM quirk for SAMSUNG MZ7TD256HAFV-000L9
Date: Thu, 25 Oct 2018 22:58:04 -0300 [thread overview]
Message-ID: <20181026015804.4120-1-diego.viola@gmail.com> (raw)
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.
