PANIC: looking up page failed for pa 0x80800000
This I solved by filtering the system-supplied memory mappings to keep.
http://dev.haiku-os.org/ticket/5193
I then get an error that some page it tries to unmap has a cache
associated.
With this workaround applied:
diff --git a/src/system/kernel/arch/ppc/arch_vm.cpp b/src/system/
kernel/arch/ppc/arch_vm.cpp
index df815ce..72f4c3c 100644
--- a/src/system/kernel/arch/ppc/arch_vm.cpp
+++ b/src/system/kernel/arch/ppc/arch_vm.cpp
@@ -130,7 +130,7 @@ arch_vm_init_end(kernel_args *args)

+ //vm_free_unused_boot_loader_range(0, 0xffffffff - B_PAGE_SIZE + 1);
return B_OK;
}
I now get:

There it hangs. The virtual address looks odd, haven't investigated
further.
I'm off for now, have fun!
