Hello,
After reading this: https://wiki.archlinux.org/index.php/TLP I stumbled with a really scary section that says:

btrfs

To avoid filesystem corruption on btrfs formatted partitions, set:
Code:
SATA_LINKPWR_ON_BAT=max_performance
That page links to the following issue: https://github.com/linrunner/TLP/issues/128

After installing and enabling TLP I didn't used with the battery for more than half an hour just in case this issue could occur.

Although the issue was reported with a Lenovo x240 (I have a Dell Latitude E6440), I'm afraid this issue may happen.

Does anyone has experienced this issue? Is the TLP default configuration safe to use with BTRFS? Does anyone tested it?
