------- Comment #16 from tj@kernel.org  2008-08-02 22:00 -------
Eh... devices_kset list is corrupt?  Strange.  It's added through
drivers/base/core.c::device_add() -> lib/kobject.c:kobject_add() ->
kobject_add_vargs() -> kobject_add_internal() -> kobj_kset_join() ->
include/linux/list.h::list_add_tail().

So, it seems loading ahci as module breaks the list.  Strange.  The list is
manipulated only through device_add() and device_del().  Can you please put
some tracing code there and see what's going on?  (ie. printk to print out
what's happening followed by infinite loop check)
