[IDE] sleeping function called from illegal context at slab.c:1347

Hello all,

looks like i tracked down yet another instance of this already famous 
message, :)
but i don't know how to fix it.

This message produced by IDE driver is IMHO 
caused by ide_init_queue() function called while holding
ide_lock spinlock in the 
init_irq() function (ide-probe.c).

Then ide_init_queue() calls blk_init_queue() 
and we have a this call chain:
    ide_init_queue() -> blk_init_queue() -> 
blk_init_free_list() -> kmem_cache_alloc()

What can we do to fix this ?

Best 
regards,
        Andrey

This is known, but thank you anyhow.
