Title:
  stuck while booting since 20.04.3 LTS  upgrade

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  
  After the upgrade to 20.04.3 LTS booting doesn't work.

  In the booting process (using the latest kernel) the computer stuck, 
  showing a purple screen:    
                                UBUNTU 20.04  
                                 . . . . .  

  (sometimes the dots indicating "i'm busy" by changing color, sometimes
  the dots are frozen)

  To get the Computer running i have to try it many times, booting with
  different kernels - if the booting process is successful it shows the
  familiar black screen with the ubuntu logo and the animated circle.

  I have already repaired the grub (option in recovery mode) and after
  that re installed ubuntu completely, but the (unsteady) booting
  problem still appears.

  Last time i could start the Computer it worked with the 5.3.0-18-generic kernel.
  These are the Kernels installed on my Computer:

  ii  linux-image-5.3.0-18-generic               5.3.0-18.19+1
  amd64        Signed kernel image generic

  ii  linux-image-5.4.0-89-generic               5.4.0-89.100
  amd64        Signed kernel image generic

  ii  linux-image-generic                        5.4.0.89.93
  amd64        Generic Linux kernel image

  
  I used ubuntu 19.04 for 2 years on this computer (HP dv 6, i7-2630qm 64bit) having no problems.
