We'll have a better solution but please try the following for now: diff --git a/include/acpi/acoutput.h b/include/acpi/acoutput.h index 6db9a6d40c85..b1196a260620 100644 --- a/include/acpi/acoutput.h +++ b/include/acpi/acoutput.h @@ -150,7 +150,7 @@ /* Defaults for debug_level, debug and normal */ -#define ACPI_DEBUG_DEFAULT (ACPI_LV_INIT | ACPI_LV_DEBUG_OBJECT | ACPI_LV_EVALUATION | ACPI_LV_REPAIR) +#define ACPI_DEBUG_DEFAULT (ACPI_LV_INFO | ACPI_LV_REPAIR) #define ACPI_NORMAL_DEFAULT (ACPI_LV_INIT | ACPI_LV_DEBUG_OBJECT | ACPI_LV_REPAIR) #define ACPI_DEBUG_ALL (ACPI_LV_AML_DISASSEMBLE | ACPI_LV_ALL_EXCEPTIONS | ACPI_LV_ALL) Thanks, Erik > > Alex > > Appendix A: Debug entry from dmesg: > > [ 1.608169] pci 0000:d9:07.0: [10b5:9733] type 01 class 0x060400 > [ 1.608212] ACPI Debug: "_HPX" > [ 1.608243] ACPI Debug: Package (Contains 0x04 Elements): > [ 1.608244] ACPI Debug: (00) Package (Contains 0x12 Elements): > [ 1.608246] ACPI Debug: (00) 0x0000000000000002 > [ 1.608247] ACPI Debug: (01) 0x0000000000000001 > [ 1.608248] ACPI Debug: (02) 0x00000000FC000FCF > [ 1.608249] ACPI Debug: (03) 0x0000000003A10000 > [ 1.608250] ACPI Debug: (04) 0x00000000FC000FCF > [ 1.608251] ACPI Debug: (05) 0x00000000004EF030 > [ 1.608253] ACPI Debug: (06) 0x00000000FFFF0E3E > [ 1.608254] ACPI Debug: (07) 0x000000000000F1C1 > [ 1.608255] ACPI Debug: (08) 0x00000000FFFFFFFF > [ 1.608256] ACPI Debug: (09) 0x0000000000000000 > [ 1.608257] ACPI Debug: (10) 0x000000000000FFF1 > [ 1.608258] ACPI Debug: (11) 0x000000000000000E > [ 1.608260] ACPI Debug: (12) 0x000000000000FFFF > [ 1.608261] ACPI Debug: (13) 0x0000000000000000 > [ 1.608262] ACPI Debug: (14) 0x00000000FFFFC010 > [ 1.608263] ACPI Debug: (15) 0x0000000000001BC0 > [ 1.608264] ACPI Debug: (16) 0x00000000FFFFC010 > [ 1.608265] ACPI Debug: (17) 0x000000000000242F > [ 1.608267] ACPI Debug: (01) Package (Contains 0x11 Elements): > [ 1.608268] ACPI Debug: (00) 0x0000000000000003 > [ 1.608269] ACPI Debug: (01) 0x0000000000000001 > [ 1.608270] ACPI Debug: (02) 0x0000000000000001 > [ 1.608271] ACPI Debug: (03) 0x00000000000001FF > [ 1.608273] ACPI Debug: (04) 0x0000000000000003 > [ 1.608274] ACPI Debug: (05) 0x0000000000000001 > [ 1.608275] ACPI Debug: (06) 0x0000000000000010 > [ 1.608276] ACPI Debug: (07) 0x0000000000000012 > [ 1.608277] ACPI Debug: (08) 0x0000000000000000 > [ 1.608278] ACPI Debug: (09) 0x0000000000000000 > [ 1.608280] ACPI Debug: (10) 0x0000000000000000 > [ 1.608281] ACPI Debug: (11) 0x0000000000000024 > [ 1.608282] ACPI Debug: (12) 0x0000000000000002 > [ 1.608283] ACPI Debug: (13) 0x0000000000000002 > [ 1.608284] ACPI Debug: (14) 0x0000000000000028 > [ 1.608285] ACPI Debug: (15) 0x00000000FFFFFFF0 > [ 1.608287] ACPI Debug: (16) 0x0000000000000006 > [ 1.608288] ACPI Debug: (02) Package (Contains 0x11 Elements): > [ 1.608289] ACPI Debug: (00) 0x0000000000000003 > [ 1.608290] ACPI Debug: (01) 0x0000000000000001 > [ 1.608291] ACPI Debug: (02) 0x0000000000000001 > [ 1.608293] ACPI Debug: (03) 0x00000000000001FF > [ 1.608294] ACPI Debug: (04) 0x0000000000000003 > [ 1.608295] ACPI Debug: (05) 0x0000000000000001 > [ 1.608296] ACPI Debug: (06) 0x0000000000000010 > [ 1.608297] ACPI Debug: (07) 0x0000000000000012 > [ 1.608298] ACPI Debug: (08) 0x0000000000000000 > [ 1.608300] ACPI Debug: (09) 0x0000000000000000 > [ 1.608301] ACPI Debug: (10) 0x0000000000000000 > [ 1.608302] ACPI Debug: (11) 0x0000000000000024 > [ 1.608303] ACPI Debug: (12) 0x0000000000000006 > [ 1.608304] ACPI Debug: (13) 0x0000000000000004 > [ 1.608305] ACPI Debug: (14) 0x0000000000000028 > [ 1.608307] ACPI Debug: (15) 0x00000000FFFFFFF0 > [ 1.608308] ACPI Debug: (16) 0x0000000000000009 > [ 1.608309] ACPI Debug: (03) Package (Contains 0x11 Elements): > [ 1.608310] ACPI Debug: (00) 0x0000000000000003 > [ 1.608311] ACPI Debug: (01) 0x0000000000000001 > [ 1.608313] ACPI Debug: (02) 0x0000000000000001 > [ 1.608314] ACPI Debug: (03) 0x00000000000001FF > [ 1.608315] ACPI Debug: (04) 0x0000000000000003 > [ 1.608316] ACPI Debug: (05) 0x0000000000000001 > [ 1.608317] ACPI Debug: (06) 0x0000000000000010 > [ 1.608318] ACPI Debug: (07) 0x0000000000000012 > [ 1.608320] ACPI Debug: (08) 0x0000000000000000 > [ 1.608321] ACPI Debug: (09) 0x0000000000000000 > [ 1.608322] ACPI Debug: (10) 0x0000000000000000 > [ 1.608323] ACPI Debug: (11) 0x0000000000000024 > [ 1.608324] ACPI Debug: (12) 0x000000000000000E > [ 1.608325] ACPI Debug: (13) 0x0000000000000008 > [ 1.608326] ACPI Debug: (14) 0x0000000000000028 > [ 1.608328] ACPI Debug: (15) 0x00000000FFFFFFF0 > [ 1.608329] ACPI Debug: (16) 0x000000000000000D > [ 1.608352] acpi_run_hpx: Type 3 record not supported > [ 1.608391] pci 0000:d9:07.0: PME# supported from D0 D3hot D3cold
