I've confirmed that by rolling back to a prior kernel (5.11.0-46-generic), the system shuts down normally.
Temp work around I used was to >sudo vi /etc/default/grub GRUB_DEFAULT=0 #GRUB_TIMEOUT_STYLE=hidden <-- comment this line GRUB_TIMEOUT=10 <-- change this line to a value between 5 and 10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" >sudo update-grub This allows me to see the GRUB boot menu and then select "Advanced options for Ubuntu" and then the kernel I want to boot -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1958724 Title: System Shutdown and resume hangs since Kernel linux- image-5.13.0-23-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.13/+bug/1958724/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
