Ok, although that didn't fix the issue, the output did give me a clue. When you put the computer into hibernate, it writes the resume file to the system swap. My system has a secondary swap file: mikey@C64serv01:~$ swapon -s Filename Type Size Used Priority /swap.img file 4194300 0 -2 /dev/sdc5 partition 4193276 0 -3
So I created the following resume file: /etc/initramfs-tools/conf.d/resume and set the RESUME variable with the blockid of the secondary swap device and it worked! mikey@C64serv01:~$ uname -r 6.8.0-49-generic mikey@C64serv01:~$ uptime 16:43:52 up 7 min, 1 user, load average: 0.30, 0.61, 0.36 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2089299 Title: Kernel updated to 6.8.0-49 black screen after grub menu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2089299/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
