I have successfully installed the rt patch follow the guide from Installing real time patch for Ubuntu 20.04 .

At the grub boot option, I am able to see the 5.19-generic and 5.19-rt options. when I enter 5.19-rt option, it will hang and shows a long list of errors, one that I caught was Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) similar to Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) . My set up is DELL desktop and Ubuntu dual boot. pls assist, thank you! I can boot all the kernel versions that I have installed except the ones with rt. The rt versions are also shown in cd /boot -> ls.

I have tried updating my nVidia driver, update grub and sudo update-initramfs -u -k .

For Dell set up,

  1. Go to Bio setup, under SATA configuration, select AHCI save and restart.

  2. Boot your boot-able kernel version, go to terminal, enter sudo gedit /etc/default/grub, edit the GRUB_CMDLINE_LINUX_DEFAULT line="quite splash" to "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

  3. Under "Software & Updates", go to Additional Drivers and select "Using Nvidia driver metapackage from nvidia-driver-(510 or your latest model)(propriety, tested)" and apply changes if you have not done so.

  4. Reboot and select your RT kernel under advance options for ubuntu. Good luck!

*Note that once you select AHCI, you might not be able to boot windows for my case, rmb to switch back to RAID ON mode for SATA Configuration mode.
