I’ve noticed that when 6.6.1 came out and it came time to reboot after it installed, I couldn’t boot into the OS anymore, it simply hangs on a black screen for about 10-15 minutes then reboots after selecting it. I’m currently on the LTS kernel which is 6.1.67-1-lts (64-bit) with no issues. I figured after updating to the latest one 6.6.6. things may be better but no. Each new kernel release, I test it with the same results.
CPU is CPU: quad core Intel Core i7-2600S (-MT MCP-) on Dell Optiplex 990 SFF PC with 16GB Ram in UEFI mode. Via either Grub or Systemd-boot. On one hand, I’m thinking that my computer’s time may have finally come up once the LTS moves to 6.6.1 but, until then, and I can procure a newer system, I’d like to see if anyone else has encountered such a thing.
I mean, no, but this probably isn’t the way you want to go about dealing with it.
If you know how to build and install your own kernel out of git, and how to run a git bisect, you could go back and identify the exact commit to the kernel that introduced your problem, which would probably do a lot to help accelerate getting the problem fixed.
