acpidump for HP zBook Studio G3

Hi there,

I’ve recently installed Linux on a brand new HP zBook Studio G3. On every boot,
I see the following messages:
[ 0.982293] ACPI Error: Field [CAP1] at 96 exceeds Buffer [NULL] size 64

I haven’t encountered issues that could be caused by these, but since they
appear on every boot and are labelled “Error”, I thought it would be a good
idea reporting them nonetheless.

I’m attaching the acpidump.

--- Comment #16 from Zhang Rui (***@intel.com) ---
Lv, this is not how the code runts

[ 0.923375] ACPI: \_PR_.CPU0: _OSC native thermal LVT Acked

You're right that this is done in ACPI processor driver. But \_PR.CPU0._OSC is
evaluated successfully!

[ 0.980457] ACPI Error: Field [CAP1] at 96 exceeds Buffer [NULL] size 64
(bits) (20160930/dsopcode-236)
[ 0.980463] ACPI Error: Method parse/execution failed [\_SB._OSC] (Node
ffff88089ece3a78), AE_AML_BUFFER_LIMIT (20160930/psparse-543)

the error actually happens when evaluating \_SB._OSC, I'm not sure but likely
in
acpi_bus_osc_support(), and please keeps on debugging this issue.
