If anyone has any objections, please let me know. ------------------ From: Bryam Vargas [ Upstream commit 462775c620197adaabc983ce847e5b9878ff4cb0 ] The PNY CS900 1TB SSD (Phison PS3111-S11, DRAM-less) drops off the bus after entering Device-Initiated Slumber during idle. With the default med_power_with_dipm policy the link goes down (SStatus 1 SControl 300) and does not recover, forcing the filesystem read-only. Forcing max_performance keeps the link stable across prolonged idle. Add a NOLPM quirk so link power management is disabled for this drive specifically, leaving it intact for other devices on the host.
