Kernel team, looks like the root cause identified by IBM (taken from description of the bug) is:

The dump target (/var/crash) is on NVMe device (also, the root disk).
But the kdump initrd is not being built with nvme driver modules.
Eventually, nvme disk is not found and kdump kernel is hitting the
initramfs shell. Using the default initrd, which has the nvme driver
modules included, dump was captured successfully.
Can someone from Canonical take a look at this and comment on why
nvme modules are not included in kdump initrd despite it being the
root disk..
Thanks
