https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D270707 --- Comment #39 from John Baldwin <jhb@FreeBSD.org> --- Ok, looking at the dump, there are two separate things going on. First, the global 'APIC' table (MADT) includes some overrides for certain IRQs: Type=3DINT Override BUS=3D0 IRQ=3D1 INTR=3D1 Flags=3D{Polarity=3Dactive-lo, Trigger=3Dedge} Type=3DINT Override BUS=3D0 IRQ=3D12 INTR=3D12 Flags=3D{Polarity=3Dactive-lo, Trigger=3Dedge} Type=3DINT Override BUS=3D0 IRQ=3D0 INTR=3D2 Flags=3D{Polarity=3Dconforming, Trigger=3Dconforming} Type=3DINT Override BUS=3D0 IRQ=3D9 INTR=3D9 Flags=3D{Polarity=3Dactive-lo, Trigger=3Dlevel} The general theme here seems to be active-lo interrupts for ISA (which is typically bizarre). Unfortunately your dump just has 'acpidump -t' output and not 'acpidump -d' output that disassembles the compiled AML. The code in acpi_resource.c is dealing with a separate bit of the ASL where individual Device() entries in= the namespace have an IRQ resource and the IRQ resource specifies the trigger m= ode and polarity. --=20 You are receiving this mail because: You are the assignee for the bug.=
