ACPI Error and power restore issue

Basic info:

• Mainboard: ASRock B150M Pro4S

• System: Arch Linux x86_64 (of course)

My box keeps bothering some ACPI Errors:

8月 05 10:31:34 esper kernel: ACPI Error: 1 table load failures, 5 successful (20170303/tbxfload-246)
8月 05 10:31:34 esper kernel: ACPI Exception: AE_NOT_FOUND, (SSDT:xh_rvp08) while loading table (20170303/tbxfload-228)
8月 05 10:31:34 esper kernel: ACPI Exception: AE_NOT_FOUND, During name lookup/catalog (20170303/psobject-241)
8月 05 10:31:34 esper kernel: ACPI Error: [\_SB_.PCI0.XHC_.RHUB.HS11] Namespace lookup failure, AE_NOT_FOUND (20170303/dswload-210)
8月 05 10:31:34 esper kernel: ACPI: Core revision 20170303

Sometimes, when the system tries to restore from sleeping mode, it might halt there without any response.

And I also encountered errors like this:

[ 7105.537203] ACPI Exception: AE_NOT_FOUND, while evaluating GPE method [_L6F] (20160831/evgpe-646)
[ 7105.538100] ACPI Error: [PGRT] Namespace lookup failure, AE_NOT_FOUND (20160831/psargs-359)
[ 7105.538102] ACPI Error: Method parse/execution failed [\_GPE._L6F] (Node ffff88026c8d64b0), AE_NOT_FOUND (20160831/psparse-543)

I tried to follow the wikis ACPI modules and DSDT to disassembly and recompile my dsdt.dsl, but failed with these Errors:

Intel ACPI Component Architecture
ASL+ Optimizing Compiler/Disassembler version 20170303
Copyright (c) 2000 - 2017 Intel Corporation

Compiler aborting due to parser-detected syntax error(s)

dsdt.dsl  17661:         }
Error    6126 -         ^ syntax error, unexpected '}'

dsdt.dsl  34445: 
Error    6126 - syntax error, unexpected $end and premature End-Of-File

ASL Input:     dsdt.dsl - 34445 lines, 1081231 bytes, 16531 keywords
Hex Dump:      dsdt.hex - 230 bytes

Compilation complete. 3 Errors, 0 Warnings, 0 Remarks, 0 Optimizations

The dsdt.dsl also gives me this warning:

    /*
     * iASL Warning: There were 17 external control methods found during
     * disassembly, but only 0 were resolved (17 unresolved). Additional
     * ACPI tables may be required to properly disassemble the code. This
     * resulting disassembler output file may not compile because the
     * disassembler did not know how many arguments to assign to the
     * unresolved methods. Note: SSDTs can be dynamically loaded at
     * runtime and may or may not be available via the host OS.
 ....

Then, I stuck there.

Re: ACPI Error and power restore issue

What machine have you? I have the same message with an ASUS P8B75M LX plus. But although I have these errors in dmesg, I see no problem with acpi. Things works as they should. Are you experiencing an issue with acpi? I thing this is harmless. This is probably due to a not compliant ACPI; for the manufacturers as long as Windows works, it is compliant.
