Maybe vexpress affects NR_IRQS or something? Also, I think we could now disable the legacy DMA init completely except for omap2 and 3. I've added a cat /proc/interrupts which should reveal whether the IRQs have changed between the two different builds. Okay, both omap4 and combined kernels indicate that the legacy DMA gets the same interrupt: 44: 0 0 4a31.gpio 18 DMA so that can't be the issue as the combined kernel spits out the warning, but the omap4 kernel doesn't. Something else is going on which causes this; the hint that it's got something to do with this is just a symptom of some other problem. -- FTTC broadband for 0.8mile line: currently at 10.5Mbps down 400kbps up according to speedtest.net. -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Yeah and there are some new clock issues for sure like I posted. Also, in your 3430-LDP logs, the DMA setup_irq related In-band Error is a mystery. I'm not seeing that with omap2plus_defconfig, but can reproduce it here with your LDP .config file. Got any ideas on that one?

Disablig CONFIG_PREEMPT makes it go away.

I tried booting my 4460 Panda - which is the closest thing to 4430SDP that I've got - on next-20141217, but I could not get it to the point where the omap-abe-twl6040 probed. It probably is the problem you are talking about as the hang does not happen if I disable ASoC ABE all together, right? I'll take a deeper look at it tomorrow, as Peter is not working ATM.
