Re: Kernel Locks During Device Probe on 7.0 Current

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.
