Comment(by andreasf):
Interestingly with {{{TRACE_MODULE}}} turned on, I get this instead:
{{{
INIT: Add preloaded old-style drivers
get_module(bus_managers/usb/v3)
initializing module bus_managers/usb/v3 (at 0x8042c644)...
...done (No such device)
usb_disk: getting module failed 0x80007007
devfs_add_preloaded_drivers: Failed to add "usb_disk"
get_module(interrupt_controllers/openpic/device_v1)
resolving module dependencies...
get_module(system/device_manager/v1)
get_module(bus_managers/pci/v1)
initializing module interrupt_controllers/openpic/device_v1 (at
0x802ed654)...
...done (No error)
get_module(system/device_manager/v1)
PANIC: arch_int_init_post_device_manager(): Found no supported PIC!
Welcome to Kernel Debugging Land...
Running on CPU 0

<kernel_ppc>:panic
<kernel_ppc>:arch_int_init_post_device_manager + 0x0324
<kernel_ppc>:int_init_post_device_mapper + 0x0024
<kernel_ppc>:_ZL5main2Pv + 0x00f0
}}}
This stems from
[source:haiku/trunk/src/system/kernel/arch/ppc/arch_int.cpp?rev=37020#L540
arch_int.cpp]. The code looks stubbed out, and I vaguely remember there
was a discussion about it when the device manager was somehow reorganized.
Will check the list archives.
Without {{{TRACE_MODULE}}} I reproducibly get the page fault but couldn't
spot an obvious cause. The last successful invocation of
{{{hash_hash_string}}} is "bus_managers/usb/v3", the next string is
damaged. Adding a NULL check for module->name doesn't help.
