This bug is awaiting verification that the linux-nvidia-
tegra/6.8.0-1001.1 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-noble-linux-nvidia-tegra' to
'verification-done-noble-linux-nvidia-tegra'. If the problem still
exists, change the tag 'verification-needed-noble-linux-nvidia-tegra' to
'verification-failed-noble-linux-nvidia-tegra'.


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]
  ACPI error can be found in kernel message:
  [    3.717920] ACPI Error: No handler for Region [SYSI] (00000000ab9e62c5) 
[IPMI] (20230628/evregion-130)

  [Fix]
  On Dell systems that have IPI0001 device, ensure IPMI region is ready
  before acpi_power_meter invokes any ACPI method.

  [Test]
  With the patch applied, no such error can be found in kernel message.
  acpi_power_meter sysfs also works correctly.

  [Where problems could occur]
  If asynchronous probe is disabled, the device drivers that probe after
  acpi_power_meter needs to wait until the completion is done, hence the
  boot time might be slower.
