When I was installing the kernel it complained about possibly missing firmware files for amdgpu. Then it failed first but I blacklisted amdgpu module and it booted.
Then I tried to install amdgpu-pro but that couldn't compile the module since it doesnt support 4.11. But I think it may have installed some firmware files and I could load the amdgpu module after boot. But, then I decided to try to disable amdgpu for 4.8 (worst idea ever!). Apparently everytime I boot 4.8, it destroys something from the hard drive. It somehow managed to loose /var/lib/dpkg first but after few reboots, completely lost the whole partition and even grub didnt start. I am never putting 4.8 again! So, for now, I can't really test anything anymore since ubuntu self- destructed itself. Luckily windows and freebsd are still working. Maybe I wait for Zesty before re-installing. About 4.11 kernel: I can tell that at last the basic keyboard was working in Linux/Ubuntu. Because with 4.4 it was skipping keypresses. The touchpad was much better, but still somewhat strange. Things like double tap and two-finger scrolling didn't work. At least mouse cursor was not jumping around randomly from time to time. The WIFI didn't work, I had to install rtlwifi_new driver from github. The hard drive was super slow, maybe even slower than before. I saw 0.6mbyte/s performance when I ran sysbench. The CPU fan was going full speed and laptop got hot. (least of my worries but it happened...) I would like to help more but I don't know what I can do at this stage. I am not even sure why amdgpu module was loaded, because the APU has sea islands gpu, I thought this was disabled by default? Did this change in 4.11? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1670624 Title: Official 16.04 HWE 4.8 kernels do not boot (4.4 was booting) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1670624/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
