--- Comment #9 from Sebastian <info@dynpages.de> ---
Hi,

just wanted to let you know that I didn't face any error related to ext4 after
disabling acpi for the sata controller.

This was my change (custom powertop settings runner started by systemd):

# Enable SATA link power management for host0   
#echo 'min_power' > '/sys/class/scsi_host/host0/link_power_management_policy';
# Enable SATA link power management for host1   
#echo 'min_power' > '/sys/class/scsi_host/host1/link_power_management_policy';


looks fine so far.


best regards


Sebastian
