ACPI Error on HP ProBook 430 G2

Hello!

Some time ago new ACPI messages appeared on console and in /var/log/messages. Like these:

ACPI Error: Needed type [Reference], found [Processor] 0xfffff800043b8980 (20161117/exresop-111)
ACPI Exception: AE_AML_OPERAND_TYPE, While resolving operands for [OpcodeName unavailable] (20161117/dswexec-498)
ACPI Error: Method parse/execution failed [\134_SB.PCI0.LPCB.EC0.PPNT] (Node 0xfffff80004396640), AE_AML_OPERAND_TYPE (20161117/psparse-560)
ACPI Error: Method parse/execution failed [\134_SB.PCI0.LPCB.EC0._Q04] (Node 0xfffff80004396c40), AE_AML_OPERAND_TYPE (20161117/psparse-560)
acpi_ec0: evaluation of query method _Q04 failed: AE_AML_OPERAND_TYPE

I'm sure that there were no such messages earlier. Suspend/resume works
for me. But after disconnecting power line hw.acpi.acline still equals
to 1. And powerd/powerdxx do not adjust CPU frequency anymore.
