Subject: [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.
