------- Comment #15 from [EMAIL PROTECTED] 2008-03-31 05:09 ------- In fact, this is not a BIOS, but only a kernel bug. With recent acpica compiler there also is no warning for the Z00x usage (did you see an error/warning here?): iasl -sa dsdt.dsl Intel ACPI Component Architecture ASL Optimizing Compiler version 20071019 [Nov 6 2007] Copyright (C) 2000 - 2007 Intel Corporation Supports ACPI Specification Revision 3.0a dsdt.dsl 254: Method (\_WAK, 1, NotSerialized) Warning 1079 - ^ Reserved method must return a value (_WAK) dsdt.dsl 1923: Method (_RMV, 0, NotSerialized) Warning 1079 - ^ Reserved method must return a value (_RMV) dsdt.dsl 4220: Name (_T_0, 0x00) Error 4081 - Use of reserved word ^ (_T_0) After fixing the _T_0 error and executing the new binary DSDT in userspace I get: acpiexec dsdt.aml ... - execute \_SB_.BAT0._BIF Executing \_SB_.BAT0._BIF ACPI Error (dsobject-0208): [Z003] Namespace lookup failure, AE_NOT_FOUND ACPI Error (dsobject-0208): [Z004] Namespace lookup failure, AE_NOT_FOUND ACPI Error (dsobject-0208): [Z005] Namespace lookup failure, AE_NOT_FOUND **** AcpiExec: Exception AE_NOT_FOUND during execution of method [_BIF] Opcode [Package] @22 **** Exception AE_NOT_FOUND during execution of method [\_SB_.BAT0._BIF] (Node 0x404d9e8) ... ACPI Error (psparse-0626): Method parse/execution failed [\_SB_.BAT0._BIF] (Node 0x404d9e8), AE_NOT_FOUND Execution of \_SB_.BAT0._BIF failed with status AE_NOT_FOUND I could imagine the NOT_FOUND case is handled more gracefully in the kernel, but I could imagine reading battery still fails, because the package includes a NULL handle even with the fixed kernel. Yakui, on the other hand site, this should be reproducable by modifying any existing laptop DSDT and add undefined Z00x objects in the _BIF there... -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
