Bug#913018: Update: bug is probably in laptop-mode-tools (linux-image-4.18.0-2-amd64: Chromium repeatedly freezes for few seconds on battery power after upgrade to 4.18.0-2)
By git bisect on linux-stable kernel tree I got to commit 0c8b7991f40d ata: libahci: Correct setting of DEVSLP register This suggested future research and I realized, that laptop-mode-tools sets drivers to lowest power mode which has setting BATT_SATA_POLICY=min_power in /etc/laptop-mode/conf.d/intel-sata-powermgmt.conf Above mentioned commit enables DEVSLP in this mode. Moreover this kernel has 'med_power_with_dipm' setting which is near 'min_power' but without DEVSLP. -- Tomáš 'ebík' Ebenlendr PF 2018.85211022324 pgp6NiHZoRXRY.pgp Description: OpenPGP digital signature
Bug#913018: Acknowledgement (linux-image-4.18.0-2-amd64: Chromium repeatedly freezes for few seconds on battery power after upgrade to 4.18.0-2)
Update: Vim (or terminal emulator - terminology) is also affected by this. When filling the bugreport, vim repeatedly freezed and then rendered new letters in wrong place (Ctrl-L was quick-fix). I did not filled this in previous report as I was not sure some Vim plugin did not cause this, but now I'm on 4.18.0-1-amd64 and happy vimming. -- Tomáš 'ebík' Ebenlendr PF 2018.84754157154 pgpvtJ_U3qmH4.pgp Description: OpenPGP digital signature
