    Kernel update to 5.11.0-2019 has killed hdmi output (Hirsuite Raspberry Pi 4)

    This is a workaround for the problem mentioned in the title.

    First of all check what is installed.

    Code:
    roger@brubeck:~$ dpkg -l | grep linux-image
    rc linux-image-5.11.0-1007-raspi 5.11.0-1007.7 arm64 Linux kernel image for version 5.11.0 on ARMv8 SMP
    rc linux-image-5.11.0-1009-raspi 5.11.0-1009.10 arm64 Linux kernel image for version 5.11.0 on ARMv8 SMP
    rc linux-image-5.11.0-1012-raspi 5.11.0-1012.13 arm64 Linux kernel image for version 5.11.0 on ARMv8 SMP
    rc linux-image-5.11.0-1015-raspi 5.11.0-1015.16 arm64 Linux kernel image for version 5.11.0 on ARMv8 SMP
    rc linux-image-5.11.0-1016-raspi 5.11.0-1016.17 arm64 Linux kernel image for version 5.11.0 on ARMv8 SMP
    ii linux-image-5.11.0-1017-raspi 5.11.0-1017.18 arm64 Linux kernel image for version 5.11.0 on ARMv8 SMP
    ii linux-image-5.11.0-1019-raspi 5.11.0-1019.20 arm64 Linux kernel image for version 5.11.0 on ARMv8 SMP
    ii linux-image-raspi 5.11.0.1019.17 arm64 Raspberry Pi Linux kernel image
    Ignore anything marked as rc (residual config).

    If 5.11.0-1017-raspi is not installed you need to install it.

    Code:
    roger@brubeck:~$ sudo apt-mark hold linux-image-raspi
    linux-image-raspi set on hold.
    roger@brubeck:~$ sudo apt-mark hold linux-image-5.11.0-1019-raspi
    linux-image-5.11.0-1019-raspi set on hold.
    roger@brubeck:~$ sudo apt-mark hold linux-image-5.11.0-1017-raspi
    linux-image-5.11.0-1017-raspi set on hold
    
    sudo flash-kernel --force 5.11.0-1017-raspi
    That should do the trick.

    If this is a thread to share a workaround, shouldn't it be marked as "Solved," so that Users can find it as such?
