Title:
Can't read battery state
Status in linux package in Ubuntu:
Triaged
Bug description:
My HP ENVY m4-1015dx Notebook PC can't read the battery state. This happens
roughly once every three sessions, with no obvious trigger, thus no way to
reproduce but to boot and wait, usually a couple of hours. The error displayed
on dmesg is the following:
ACPI Error: Method parse/execution failed [\_SB.PCI0.LPCB.EC0.MMRD] (Node
ffff8802468b4f50), AE_AML_INFINITE_LOOP (20150930/psparse-542)
ACPI Error: Method parse/execution failed [\_SB.PCI0.LPCB.EC0.RDMB] (Node
ffff8802468b5938), AE_AML_INFINITE_LOOP (20150930/psparse-542)
ACPI Error: Method parse/execution failed [\_SB.PCI0.LPCB.EC0.RDMW] (Node
ffff8802468b5960), AE_AML_INFINITE_LOOP (20150930/psparse-542)
ACPI Error: Method parse/execution failed [\_SB.PCI0.LPCB.EC0.BAT0._BST]
(Node ffff8802468b54d8), AE_AML_INFINITE_LOOP (20150930/psparse-542)
This makes every process that depends on reading battery state hang
indefinitely, including suspend and shutdown. It is my understanding
that \_SB.PCI0.LPCB.EC0.MMRD is the PCI Node of Memory Read 32-bit
double word, and that these other nodes reference it in their
definitions. In the session I share (dmesg), no event gets registered
in dmesg for several minutes before these errors. As I said, no
obvious trigger.
Also, perhaps related, I find two other ACPI parsing/execution errors that
repeat on every boot and frequently show on dmesg without any visible effect:
ACPI Error: Method parse/execution failed [\_SB.PCI0.LPCB.EC0.ACCR] (Node
ffff8802b68b4ed8), AE_AML_INFINITE_LOOP (20150930/psparse-542)
ACPI Error: Method parse/execution failed [\_SB.PCI0.ACEL._STA] (Node
ffff8802b68b90a0), AE_AML_INFINITE_LOOP (20150930/psparse-542)
I haven't been able to find anything on the first node.
This has been reproducible on kernel 3.19.
Maybe worth mentioning. When disassembling DSDT from IASL I get a warning:
iASL Warning: There were 6 external control methods found during disassembly,
but additional ACPI tables to resolve these externals were not specified. The
resulting disassembler output file may not compile because the disassembler did
not know how many arguments to assign to these methods.
