I have been working upstream to get this fixed on the nvme driver, but it might still take some time, I already have done a back and forth with hch. Will send a v3 later this month.

Meanwhile, there are multiple workarounds we documented so far in the bug, namely:

1) Disable nvme multipath, which is done by setting the multipath module
parameter for the nvme module on modprobe.d config files, regenerate
initrd, reboot, then regenerate kdump initrd.

2) Use MODULES=most instead of MODULES=dep on
/etc/kernel/postinst.d/kdump-tools and regenerate kdump initrd.

3) Force insert nvme modules into kdump initrd. Namely, just copy the
/boot/ initrd file to replace the one in /var/lib/kdump/.
