[Timo Aaltonen]

Hello Kevin, or anyone else affected,

Accepted linux-firmware into jammy-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/linux-
firmware/20220329.git681281e4-0ubuntu3.34 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-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. 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:
  Error: out of memory while booting after installing the linux-firmware
  in proposed

  Fix Released
Status in linux-firmware package in Ubuntu:
  Fix Released
Status in linux-firmware source package in Jammy:
  Fix Committed

Bug description:
  [Impact]

  I found that there are some machines in cert lab can't boot after
  installing the linux-frimware in proposed with 6.8.0-40 kernel.

  After selecting booting with the 6.8.0-40 kernel, it shows error: out
  of memory on the screen then freeze.

  There aren't any journal logs available, since they froze at very
  early stage.

  Following are the machines got impacted for now
  https://certification.canonical.com/hardware/202306-31695/
  https://certification.canonical.com/hardware/202306-31696/

  Problem details:

  The linux-firmware package provides new (gigantic) firmware blobs and
  symlinks to directories that contain those. initramfs-tools can't
  handle the directory symlinks and puts multiple copies of the same
  blobs into the initrd blowing it up to a size where it becomes
  problematic on some machines.

  [Test Case]

  Verify the affected machine boots again with the updated firmware
  package.

  Install updated linux-firmware package and confirm that there are no
  duplicate firmware files in /lib/firmware and inside the initrd. Also
  verify that there are no broken symlinks.

  [Where Problems Could Occur]

  If the new symlinks are broken, we end up with drivers not finding
  their firmwares which results in non-functional HW components.

  [Notes]

  This is not a general solution for the problem of the ever growing
  size of the initrd. It just alleviate it some.
