Hi,
I've been trying use certain features offered by tlp (like discharging
and re-calibration) but getting an error. Did a little digging and found
out some clues as to what's going on.
output of "tlp-stat -b":
> tpacpi-bat (acpi_call) = inactive (kernel error)
searching in the logs using journalctl I got:
> acpi_call: loading out-of-tree module taints kernel.
> 440 kernel: acpi_call: module verification failed: signature and/or
required key missing - tainting kernel
I'm using a Thinkpad T440, secureboot disabled. Kernel: /5.15.0-2-amd64./
Is this a bug?
