I installed Manjaro in a device with a Samsung 830 SSD which has a buggy firmware and causes the lockups and hard resets of the SATA link, all because LPM is enabled and there is no way to disable that in the BIOS.
I managed to stop the errors issuing the following to disable LMP:
#echo "max_performace" > /sys/class/scsi_host/host0/link_power_management_policy
Is there a kennel parameter to accomplish the same or some other method to apply this at boot time?
Thanks.
