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.

This bug is awaiting verification that the linux-oem-6.5/6.5.0-1021.22 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-linux-oem-6.5' to 'verification-done-jammy-linux-oem-6.5'. If the problem still exists, change the tag 'verification-needed-jammy-linux-oem-6.5' to 'verification-failed-jammy-linux-oem-6.5'.

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!
