This bug is awaiting verification that the linux/5.15.0-57.63 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-jammy' to 'verification-done-jammy'. If the problem
still exists, change the tag 'verification-needed-jammy' to
'verification-failed-jammy'.

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!

Bug description:
  [Impact]
  Need this patch in so a BIOS upgrade won't cause issues on HP laptops.

   platform/x86: hp_wmi: Fix rfkill causing soft blocked wifi

  After upgrading BIOS to U82 01.02.01 Rev.A, the console is flooded
  strange char "^@" which printed out every second and makes login
  nearly impossible. Also the below messages were shown both in console
  and journal/dmesg every second:

  usb 1-3: Device not responding to setup address.
  usb 1-3: device not accepting address 4, error -71
  usb 1-3: device descriptor read/all, error -71
  usb usb1-port3: unable to enumerate USB device

  Wifi is soft blocked by checking rfkill. When unblocked manually,
  after few seconds it would be soft blocked again. So I was suspecting
  something triggered rfkill to soft block wifi.  At the end it was
  fixed by removing hp_wmi module.

  The root cause is the way hp-wmi driver handles command 1B on
  post-2009 BIOS.  In pre-2009 BIOS, command 1Bh return 0x4 to indicate
  that BIOS no longer controls the power for the wireless devices.

  [Test case]

  test on a HP laptop with the new BIOS

  [Where problems could occur]

  from the commit:
    * In pre-2009 BIOS, command 1Bh return 0x4 to indicate that
    * BIOS no longer controls the power for the wireless
    * devices. All features supported by this command will no
    * longer be supported.

  anyone running a laptop with obsolete pre-2009 BIOS probably won't
  notice the missing feature at this point.
