I always keep default APM_level = 128
When I use Porteus in copy2ram I always spin down the/dev/sda with hdparm -y ou -Y
And in normal case/dev/sda doesn't rotate while I won't mount/dev/sdax neither attempt to access files system.
More over dmessg doesn't record any line after the 60 second in exception when I access sdax partition or when I switch on an usb device...
But on the Fujitsu laptop it is always starting /dev/sda every 600 second with 4 extra entry on dmessg
Code: Select all
[ 6039.363528] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
[ 6039.364129] ata1.00: ACPI cmd f5/00:00:00:00:00:a0(SECURITY FREEZE LOCK) filtered out
[ 6040.845310] ata1.00: ACPI cmd f5/00:00:00:00:00:a0(SECURITY FREEZE LOCK) filtered out
[ 6040.845462] ata1.00: configured for UDMA/100
What does it mean ?
Why to link up ata1 sata and say security freeze lock only on Fujitsu laptop?
