Hi All...Have A315-41-R8UU Bios v. 1.11. What I have tested: Debian 9 Stretch [with firmware] kernel 4.9x, xfce4...This boots, without issue, but haven't tested out it's stability long-term. No boot args needed. Brightness controls do not work. Also tested openSUSE Leap 15, no boot args, KDE edition. Brightness controls do not work. Will eventually freeze after some time idle. On both distros, get the same acpi bugs during boot. To try and mitigate some of the BIOS bugs, I turned off WoL, SATA ch1, Open Lid resume, Disable TPM (would get tpm errors on boot), D2D Recovery disabled, secure boot disabled, and basic touchpad. Oddly, when attempting to install xubuntu 18 LTS or debian 9 testing, that's when I get all the errors described above. I have added the ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=0:00.2 to grub when trying to run the installers, and they will indeed run, at low resolution. Why would older kernels run without the boot params for acpi, while these newer kernels will not? Maybe this can help someone? This thing so far, is a paperweight.
