Title:
[SRU] ucsi drivers missing in initramfs
Status in initramfs-tools package in Ubuntu:
Fix Released
Status in initramfs-tools source package in Jammy:
New
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:
$ zstdcat /boot/initrd.img-5.19.0-46-generic >/tmp/initrd
$ lsinitramfs /tmp/initrd |grep typec_ucsi.ko
cpio: premature end of archive
After installing the updated initramfs-tools package, your current initramfs
should be automatically rebuilt and pick up typec_ucsi.ko:
$ zstdcat /boot/initrd.img-5.19.0-46-generic >/tmp/initrd
$ lsinitramfs /tmp/initrd |grep typec_ucsi.ko
usr/lib/modules/5.19.0-46-generic/kernel/drivers/usb/typec/ucsi/typec_ucsi.ko
cpio: premature end of archive
[ 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%.
