You are hitting the BUG_ON() in line 909, whereas Mathieu was hitting something further up in the same routine. However I agree that they look suspicious. Both look as if something is corrupting the rpc_task structure. In your case, a debugging tag that is only ever touched by the RPC code at the very start and very finish of the call is being changed, which points at something like a use-after-free issue. Hmm... I note that you are both running with the SLUB allocator. Any chance you can reproduce using SLAB (and with the SLAB debugging enabled)?
