Hello Loïc, or anyone else affected,
Accepted initramfs-tools into lunar-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/initramfs-
tools/0.142ubuntu2.1 in a few hours, and then in the -proposed
repository.
Please help us by testing this new package. See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed. Your feedback will aid us getting this
update out to other Ubuntu users.
If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
lunar to verification-done-lunar. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-lunar. In either case, without details of your testing we will
not be able to proceed.
Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in
advance for helping!
N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
[SRU] ucsi drivers missing in initramfs
Status in initramfs-tools package in Ubuntu:
Fix Released
Status in initramfs-tools source package in Jammy:
Fix Committed
Status in initramfs-tools source package in Lunar:
Fix Committed
Bug description:
[Impact]
Some systems rely on a USB type-C UCSI connection; without the
corresponding driver in the initramfs, USB storage might not be
accessible. This is notably affecting NVIDIA Tegra systems such as
Jetson AGX or the IGX and prevents completing USB boot for
installation purposes.
The initramfs-tools package has a list of relevant USB drivers to
include for the default MODULES=most configuration, but didn't list
the recently introduced ucsi one.
[ Test Plan ]
The -generic kernel and probably all kernel flavors contain the ucsi driver. On jammy system, you can verify the current initrd doesn't contain typec_ucsi.ko by decompressing the initramfs and listing its files:
$ lsinitramfs /boot/initrd.img-5.19.0-46-generic | grep typec_ucsi.ko
After installing the updated initramfs-tools package, your current initramfs should be automatically rebuilt and pick up typec_ucsi.ko:
$ lsinitramfs /boot/initrd.img-5.19.0-46-generic | grep typec_ucsi.ko
usr/lib/modules/5.19.0-46-generic/kernel/drivers/usb/typec/ucsi/typec_ucsi.ko
[ Where problems could occur ]
This is making the initramfs slightly bigger. In my testing,
typec_ucsi.ko was 99913B and /boot/initrd.img-5.19.0-46-generic grew
by 93403B from 122298948B to 122392351B, so by less than 0.08%.
