Hello.
Reading the Arch wiki about btrfs says that there is a data corruption issue with TLP that is solved by changing
SATA_LINKPWR_ON_BAT=max_performance.
I am going to change it on the laptop but do i need to change this on the desktop? I can’t understand if the issue is only when on battery.Also does anyone know if there are any similar issues with laptop-mode-tools? The wiki has nothing on it (Aggressive Link Power Management seems to be the issue with TLP) but just to be sure…

If you aren’t getting error messages it’s unlikely you’re affected. Check here:

http://linrunner.de/en/tlp/docs/tlp-faq.html#warnings :

Which kind of warnings does “tlp-stat -w” check for?

Currently the command checks the kernel log for errors possibly caused by the settings for SATA ALPM.

What should I do if warnings are shown?

TLP’s default setting on battery

SATA_LINKPWR_ON_BAT=min_power

is optimimized for maximum power saving. Try to use less aggressive values:

SATA_LINKPWR_ON_BAT=medium_power

or

SATA_LINKPWR_ON_BAT=max_performance

or disable the setting completely – see SATA ALPM.

Don’t forget to reboot before checking again.

The same applies to SATA_LINKPWR_ON_AC if you changed the default setting.

SATA_LINKPWR_ON_AC is already on max_performance. Rebooting i’ll check if all is well. Thank you.
