Public bug reported:
[Impact]
Kernels newer than 5.4 cannot be analyzed using the crash tool from Focal.
[Test case]
Install a linux dbgsym package and run the command below, replacing
vmlinux-5.11.0-1023-azure by the appropriate kernel debug file.
crash /usr/lib/debug/boot/vmlinux-5.11.0-1023-azure /proc/kcore
[Potential regression]
crash might fail to work with older kernels, or some of its commands might not
work anymore.
