Lan Tianyu <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |NEEDINFO CC| |[email protected] Assignee|acpi_power-video@kernel-bug |[email protected] |s.osdl.org | --- Comment #1 from Lan Tianyu <[email protected]> --- Check the dsdt and ssdt5 table, both \_SB.PCI0.PEG0 and \_SB.PCI0.P0P2 have same addr(0x00010000) but they don't have _STA method. Before commit 33f767, acpi_get_child() returned the last one when there were devices with the same _ADR. After the commit, it returned the first one. This may explain that the handle became \_SB.PCI0.P0P2 from \_SB.PCI0.PEG0. commit c7d9ca should resolve the problem since it will return the last one if all devices don't have _STA(Here is the case.). I notice commit 33f767 changed do_acpi_find_child() as post_order_visit callback for acpi_walk_namespace() from pre_order_visit. This may be the cause. I will produce a debug.patch. Please have a try. Device (P0P2) { Name (_ADR, 0x00010000) // _ADR: Address Method (_PRT, 0, NotSerialized) // _PRT: PCI Routing Table { If (PICM) { Return (AR02 ()) } Return (PR02 ()) } } Scope (\_SB.PCI0) { Name (LTRS, Zero) Name (OBFS, Zero) Device (PEG0) { Name (_ADR, 0x00010000) // _ADR: Address OperationRegion (PEGR, PCI_Config, 0xC0, 0x30) Field (PEGR, DWordAcc, NoLock, Preserve) { Offset (0x02), PSTS, 1, Offset (0x2C), GENG, 1, , 1, PMEG, 1 } ... -- You are receiving this mail because: You are watching the assignee of the bug. ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
