this issue is a bit different. The problem is that the irq warning message (which is harmless) is printed from an atomic context. In the next release i'll try something different: simply dont print to the fbcon if the kernel is in an atomic context. This will reduce the utility of fbcon when debugging kernel crashes, but it should avoid this assert (and potential problems resulting out of it). Other types of consoles (serial, text, netconsole) will still try to output everything, independently of atomicity. (of these, only netconsole wants to reschedule.)
