After it was pretty clear a stable kernel wasn't coming any time soon for 19.10 I gave up and took a dangerous leap. The only way I was going to get a 5.4 kernel was to move to 20.04. It was dangerous and I had to get there through a do-release-upgrade -d. Highly not recommended if you don't know what you are doing. I basically backed everything up and planned on things failing. I did it from the command line from multiple root shells launched ahead of time using screen in case X died.
I had Virtualbox 6.1.6 installed before I went through my upgrade. It was not a clean upgrade as something as part of the upgrade process forced the uninstall of Virtualbox 6.1.6. I suspect it was because some of the dependencies of Virtualbox 6.1.6 only existed in Universe on focal Virtualbox 6.1.6 was uninstalled as part of the upgrade to 20.04. The upgrade actually blew up but I knew enough to recover. That blew a lot of things out of the water and was not listed on the upgrade screen or I would not have proceeded. I shutdown virtualbox and let it be temporarily uninstalled. Then I did a apt-get dist-upgrade and once that completed I tried to install Virtualbox 6.1.6 again but failed due to missing dependencies. I regretted doing an apt-get autoremove --purge just before hand. I had to manually download and install libqt5opengl5:amd64 for focal and then an apt-get install -f was able to fix python and in turn Virtualbox 6.1.6. Then once Virtualbox installed things worked again. After all the hell on 19.10 suddenly all my problems are gone. My NIC drivers still work thanks to the updated Intel e1000e 3.8.4 release DKMS package which Intel engineering kindly provided. That badly needs to be native to Ubuntu 20.04 as the kernel driver at least back on 5.3.0 didn't work for me. I have seen no i915 hangs with the kernel 5.4.0-28-generic. I haven't seen any flaky Bluetooth behavior that led to kernel panics but to be fair I didn't need to use Bluetooth audio sink on 20.04 as my HDMI audio pass-through works properly again! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872001 Title: 5.3.0-46-generic - i915 - frequent GPU hangs / resets rcs0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872001/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
