I had the same issue, similar hardware I have had to revert back to the previous kernel version 5.15.0.-107 there was some errors in the log that pointed at the AMD GPU
if you need to boot from the previous kernel you will need to tap shift when the device boots, go into advanced options and select kernel .107 generic I then changed my grub menu sudo nano /etc/default/grub changed GRUB_DEFAULT=0 to GRUB_DEFAULT="1>2" (this tells grub to boot into advanced options and then the second linux kernel image, .107 at least for me ) save the file sudo update-grub sudo reboot The device then booted successfully into the working .107 then i removed the .112 kernel sudo apt remove linux-image-5.15.0-112-generic sudo apt remove linux-headers-5.15.0-112 sudo update-grub I also put a hold on .112 sudo apt-mark hold linux-image-5.15.0-112-generic sudo apt-mark hold linux-image-5.15.0-112-generic apt-mark showhold I then changed grub back to GRUB_DEFAULT=0 I have attached a full log for the developers perusal ** Attachment added: "log.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2068738/+attachment/5787652/+files/log.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2068738 Title: Kernel update 5.15.0-112 might cause severe problems with specific AMD GPUs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2068738/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
