Comment 7 for bug 1848236

I've verified this bug using the following procedure:

a) For all the required series, download the "debian-installer" source package and all of its build dependencies;
b) Modify the build/config/amd64.cfg to use the -proposed version of the kernel for the series you're verifying;
c) Run make "build_netboot" to create the installer images;
d) Check the generated initrd.gz to see if the kernel there contains the right module.

The results from my testing:
For Xenial:
# zcat initrd.gz | cpio -tdm | grep iwlmvm
lib/modules/4.4.0-167-generic/kernel/drivers/net/wireless/iwlwifi/mvm/iwlmvm.ko

For Bionic:
# zcat initrd.gz | cpio -tdm | grep iwlmvm
lib/modules/4.15.0-68-generic/kernel/drivers/net/wireless/intel/iwlwifi/mvm/iwlmvm.ko

For Disco:
# zcat initrd.gz | cpio -tdm | grep iwlmvm
lib/modules/5.0.0-34-generic/kernel/drivers/net/wireless/intel/iwlwifi/mvm/iwlmvm.ko

For Eoan:
# zcat initrd.gz | cpio -tdm | grep iwlmvm
lib/modules/5.3.0-21-generic/kernel/drivers/net/wireless/intel/iwlwifi/mvm/iwlmvm.ko

Cheers,
