Bug#1012440: linux-image-amd64: Long time to load ACPI module battery.ko
Package: linux-image-amd64
Version: 5.10.113-1
Severity: normal
X-Debbugs-Cc: macgyver0@gmail.com
Dear Maintainer,
the boot process of my new laptop is heavily slowed down by the ACPI modules loading.
I narrowed down to the battery.ko module: it takes about 8.4 s to load, during which the system is apparently not doing anything and just waiting.
...
[ 1.026951] SCSI subsystem initialized
[ 1.030514] ACPI: Power Button [PWRF]
[ 9.460317] battery: ACPI: Battery Slot [BAT1] (battery present)
[ 9.465637] intel-lpss 0000:00:15.0: enabling device (0000 -> 0002)
...
Consider that 8 s in my case is very long time since the entire boot process (without loading that module) takes only ~10s.
I am on a new Lenovo laptop with i5-1035G1 and Samsung SSD 256 GB.
I do not see relevant module options to try and I have no other debug informations that could be useful: if you want more information just ask of course.
As a temporary solution I rebuilt the initrd without that module and I am loading it, by a custom systemd unit, in background as soon as possible, so that in the meantime the boot process can continue while it's loading and I can also login and start my DE (xfce).
Regards,
Luca
