Okay, I've recompiled the GENERIC 7.0-current kernel
with VERBOSE_SYSINIT. ddb is in the kernel too.
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? Thanks in advance.
