Why is ALPM enabled in fedora 27 by update? (was SATA errors (only) when on battery) - users - Fedora Mailing-Lists

Thursday, 8 February 2018

Hi again,

...
 Recently my rather old HP Elitebook 2540p with an SSD in the upgrade
 bay running Fedora 27 stopped booting when not plugged on.
 The laptop is equipped with an 1st gen Intel Core i5 540M  processor
 as well as an "Intel Corporation 5 Series" SATA controller (lspci
 output attached). 
The more I analyze this issue, the more I think it is caused by ALPM
(agressive link power management).
When I switched in BIOS the SATA mode from AHCI -> IDE everthing
worked like before, so does the laptop when I am connected to wall
power.

However I wonder, did ALPM enablement accidently slip into stable
Fedora-27 updates?
I thought ALPM was targeted for Fedora-28:
