[system76_acpi] Charging threshold ability missing
The charge_control_start_threshold
& charge_control_end_threshold
entries are missing from /sys/class/power_supply/BAT0/
on my System76 Gazelle 17 (gaze17-3060-b). They are present with Linux <= 6.5.
I've talked to Aaron Honeycutt with System76 support and he can neither reproduce it on Arch nor NixOS with Linux 6.6.1. I've compared the 6.5 & 6.6 configs and don't see anything that might have caused it. CONFIG_SYSTEM76_ACPI=m
is present on both.
The module is loaded:
❯ lsmod | grep system76
system76_acpi 20480 0
EDIT: It may be a kernel regression after all.
Aaron from System76 responded again:
I have a few other customers that seem to have the same issue but they are on Arch itself.
