I can't answer your question about battery life according to the parameters, I did not test that.
If you're running RavenRidge on Ubuntu, you will have to fight the CPU (Ryzen's CPU lock ups: https://bugzilla.kernel.org/show_bug.cgi?id=196683 ) and also amdgpu, because they're still working on it. 1st: Get your CPU working: AFAIK: disable SMT (seems to have some weird clocking side effects – I didn't figure that out) OR set CPU govenor to "powersafe" (will make the Ryzen's clock get kind of fixed to max 1,6 or 2ghz) OR idle=nomwait (my favorite solution so far) While you're testing the CPU, try to disable amdgpu by kernel-parameter "nomodeset" to exclude any amdgpu-issues while testing. My testcase-setup was: Let Palemoon (Firefox-Fork) autoplay random videos on Youtube, because it causes some partial load and needs no user actions. Freezes occurred between 4 minutes and 3 hours. 2nd: Get amdgpu working: Well. You'll have a lot of fun finding a solution, that works for you! *Start reading vega-based articles on phoronix. *Then cry a lot. *Then try out different versions of mesa/LLVM ( https://launchpad.net/~paulo-miguel-dias ). *Then cry a lot. I'm was testing Padoka stable ppa with Kernel 4.15 and 4.17.2 (mainline, installed via ukuu) and still had freezes (GUI was frozen, but sound was going on and REISUB was possible) until I copied new firmware from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/amdgpu?id=66e1b33efe227432956136dd46bdb2a9b7f38a27 Just download all raven_*.bin files and put them to /lib/firmware/amdgpu/ and reboot. My freezes went away, no matter what Kernel (4.15 or 4.17) I'm using. But if I'm running: "update-initramfs -u" booting will freeze at: "switching to amdgpudrmfb from EFI VGA" Solution is to boot with "nomodeset" and run: "apt remove linux-firmware" "apt install linux-firmware" "update-initramfs -u" and then copy the new firmware again and reboot. But I just ran into that issue, so that "solution" is brand new and not much tested. Better have backups, as you always should have. Running RavenRidge on Ubuntu is a bit of a kerfuffle. ** Bug watch added: Linux Kernel Bug Tracker #196683 https://bugzilla.kernel.org/show_bug.cgi?id=196683 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1772081 Title: HP x360 - Ryzen 2500U Locks up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1772081/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
