Mobile phone companies, Linux Distros, embedded Linux deployments, etc all generally like the idea of installing one major version of Linux (e.g. 4.9) and sticking with it for the lifetime of their product.
This, and following stories tell how week to week testing of Linux kernels is going, what we’ve found, or better, not found as the kernel versions tick by.
We test using two host user spaces, open embedded and Android.
4.9.152, 4.14.95, 4.20.4
Reported crashes in v4.20.3–15-g5592f5bf010b which were intentional ‘canaries’ (the canary successfully died)
Reported no regressions in <24h
Reported no regressions in <48h

4.19.16 — Note USB OTG regression and potential eMMC issue documented in the bugs section
4.4.170 — no regressions
4.9.150 — no regressions
Android 8.1–4.4 on HiKey, Android 8.1, 4.14 on X15

Android 9/P + automerged latest version of LTS 4.4, 4.9, 4.14, 4.19 + HiKey + Latest LTP
This new combination is a work in progress to pull in latest LTP from AOSP-master, as well as using the combination of Android Common + HiKey Linaro (auto merged). It triggers automatically when Android Common is updated right after a new LTS release is merged. This combo thus gives everyone great visibility to test results nearly immediately after an new LTS is available.
We have initial data but are not sharing them as part of this report yet.
AOSP-master tracking with 4.4, 4.9, 4.14, 4.19 on HiKey
These builds are being reworked / repackaged so we’ll have data to report next week.
