Booting with the GENERIC kernel built with those options and with ACPI enabled, I get: subsystem 9000000 tcov_init(0)... done. subsystem a000000 synch_setup(0)... done. subsystem a800000 run_interrupt_driven_config_hooks(0)... And then the system hangs. I cannot break into ddb with Ctrl+Alt+Esc at this point. If I disable ACPI and boot with the same kernel, I get: subsystem 9000000 tcov_init(0)... done. subsystem a000000 synch_setup(0)... done. subsystem a800000 run_interrupt_driven_config_hooks(0)... firewire0: 2 nodes, maxhop <=1, cable IRM=1 (me) firewire0: bus manager 1 (me) And it hangs there. Any ideas on what I should do next?
