I'm *guestimating* that the following patch will fix this problem. Let 
me know if you use it wether it makes this problem go away or not. Note 
that to me at least, blk_init_queue() should be responsible for 
initializing this memory not the driver. Either way, something has to 
initialize request_queue.kobj.kset otherwise I think this is the result 
when the kset field can be any value.
