Ancient Gravis Ultrasound Plug&Play sound card. >Description: gusc_attach() causes panic by calling device_get_parent(0) Boot and trap messages: unknown: <Synth & Codec> can't assign resources gusc0: <Gravis UltraSound Plug & Play OPL> at port 0x388-0x389 irq 5 on isa0 gusc1: <Gravis UltraSound Plug & Play MIDI> at port 0x330-0x331 irq 10 on isa0 Fatal trap 12 fault virtual address = 0x8 ( == 0->parent ) instruction pointer = 0x8:0xc01913d6 (in device_get_parent()) stack pointer = 0x10:0xc0458ae0 frame pointer = 0x10:0xc0458ae0 ...
