controller: ahci0 at pci0 dev 18 function 0 "Intel Gemini Lake AHCI" rev 0x06: msi, AHCI 1.3.1 problematic drive: sd1 at scsibus1 targ 1 lun 0: <ATA, Samsung SSD 860, RVT0> system drive(working fine): sd0 at scsibus1 targ 0 lun 0: <ATA, AMD R5MS512G5, W082>
the samsung ssd appears to fall into a deep sleep during idle and fails to wake
up. the device remains visible in the system, but all i/o operations hang
indefinitely until a hard reboot. this issue was not present in 7.7.
the system drive(amd ssd) is unaffected, likely because it is constantly active
and never enters an idle sleep state. SMART data for the samsung drive shows an
increasing POR_Recovery_Count, suggesting hardware resets or power loss on the
link level.
has anyone else experienced similar regressions with samsung and gemini lake on
7.8?
also: any tips on how to disable LPM/NCQ specifically for this drive without
dropping the entire controller to sata1 mode(using ahci flag 0x1)?
