nysander Posted June 17, 2018 Share Posted June 17, 2018 Hello. I start patching my laptop Lenovo W540 (as in signature) and found that first add-on SSDT which I load fails because of: Quote 2018-06-17 02:25:49.063022+0200 0x71 Default 0x0 0 0 kernel: (AppleACPIPlatform) SSDT 0x000000007CEAA000 00045B (v02 W540 XHC 00000000 INTL 20180427) 2018-06-17 02:25:49.063023+0200 0x71 Default 0x0 0 0 kernel: (AppleACPIPlatform) SSDT 0x000000007CEAA000 00045B (v02 W540 XHC 00000000 INTL 20180427) 2018-06-17 02:25:49.127093+0200 0x71 Default 0x0 0 0 kernel: (AppleACPIPlatform) ACPI Error: 2018-06-17 02:25:49.127094+0200 0x71 Default 0x0 0 0 kernel: (AppleACPIPlatform) ACPI Error: 2018-06-17 02:25:49.127412+0200 0x71 Default 0x0 0 0 kernel: (AppleACPIPlatform) [\_SB_.PCI0.XHC_._DSM] 2018-06-17 02:25:49.127412+0200 0x71 Default 0x0 0 0 kernel: (AppleACPIPlatform) [\_SB_.PCI0.XHC_._DSM] 2018-06-17 02:25:49.127990+0200 0x71 Default 0x0 0 0 kernel: (AppleACPIPlatform) Namespace lookup failure, AE_ALREADY_EXISTS 2018-06-17 02:25:49.127991+0200 0x71 Default 0x0 0 0 kernel: (AppleACPIPlatform) Namespace lookup failure, AE_ALREADY_EXISTS Purpose of this SSDT is static USBInjectAll ports and defining power to this ports as plain DSDT lacks >500mA of power when connecting devices. Can you tell me what I am doing wrong? Below my debug package with all relevant data. https://www.dropbox.com/s/0g929zyl07r8q3w/debug_12482.zip?dl=0 Link to comment Share on other sites More sharing options...
