Package: laptop-mode-tools
Version: 1.72-2
Severity: important
Tags: patch
Laptop-mode-tools puts SATA drives in DEVSLP on battery. Waking drives
then takes several seconds, rendering all disk-using applications (web browser,
Vim editor, ...)
unresponsive for few seconds every often.
Reason is that recent kernels (linux-image-4.18.0-2, i.e. kernels 4.18.9 and
4.19)
sets AHCI devices in DEVSLP mode when link_management_power_policy is
set to 'min_power'. These kernels have 'med_power_with_dipm' setting
which is near 'min_power' but without DEVSLP. This setting is introduced
in kernel 4.15.
I replaced line
BATT_SATA_POLICY=min_power
with line
BATT_SATA_POLICY=med_power_with_dipm
in
/etc/laptop-mode/conf.d/intel-sata-powermgmt.conf
and now everything works again. I suggest setting default to
med_power_with_dipm as there will be only few users with kernel older
than 4.15 especially when buster will become stable. Second option is
to autodect support for 'min_power' based on kernel release (uname -r).
