Actually, I didn't have bootverbose set. The same GENERIC kernel, with bootverbose and ACPI set, gives: subsystem 9000000 tcov_init(0)... done. subsystem a000000 synch_setup(0)... done. subsystem a800000 run_interrupt_driven_config_hooks(0)...rr232x: no controller detected acpi_acad0: acline initialization start acpi_acad0: On Line acpi_acad0: acline initialization done, tried 1 times battery0: battery initialization start battery0: battery initialization done, tried 1 times then hangs. With bootverbose set and with ACPI off, I get: subsystem 9000000 tcov_init(0)... done. subsystem a000000 synch_setup(0)... done. subsystem a800000 run_interrupt_driven_config_hooks(0)... rr232x: no controllers detected. firewire0: 2 nodes, maxhop <=1, cable IRM=1 (me) firewire0: bus manager 1 (me) and stop. I've compiled a new GENERIC kernel. The new 7.0-current kernel has VERBOSE_SYSINIT and ddb, and I've compiled out all Firewire devices (firewire, sbp, fwe, fwip, dcons, and dcons_crom.) The new kernel, with bootverbose and ACPI set, gives: subsystem 9000000 tcov_init(0)... done. subsystem a000000 synch_setup(0)... done. subsystem a800000 run_interrupt_driven_config_hooks(0)...rr232x: no controller detected acpi_acad0: acline initialization start acpi_acad0: On Line acpi_acad0: acline initialization done, tried 1 times battery0: battery initialization start then hangs. With bootverbose set and with ACPI off, I get: subsystem 9000000 tcov_init(0)... done. subsystem a000000 synch_setup(0)... done. subsystem a800000 run_interrupt_driven_config_hooks(0)... rr232x: no controllers detected. and then it hangs. I don't think Firewire is causing this, unfortunately. At least not directly. Thank you very much for your help, by the way. --- Kip Macy <kip.macy@gmail.com> wrote: > Try taking out firewire.
