This bug is awaiting verification that the linux-gcp/6.2.0-1017.19
kernel in -proposed solves the problem. Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-lunar-linux-gcp' to 'verification-done-lunar-
linux-gcp'. If the problem still exists, change the tag 'verification-
needed-lunar-linux-gcp' to 'verification-failed-lunar-linux-gcp'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

  *
  https://lore.kernel.org/lkml/20230912002703.3924521-1-acdun...@google.com/

  [Test Case]

  * Patches relatively isolated and maintain similar checking
  functionality, just earlier in boot. Likely a low chance of
  regression.
