Subject: 3.1-rc3 fails to boot on my pandaboard

Hi,

There seems to be a problem with 3.1-rc3, which prevents it from booting
on my PandaBoard (ARM OMAP4).

3.1-rc2 works fine, so I have bisected the problem and it turns out to
be caused by this:

commit f3637a5f2e2eb391ff5757bc83fb5de8f9726464
Author: Sebastian Andrzej Siewior <bigeasy@...utronix.de>
Date:   Thu Jul 7 22:32:17 2011 +0200

    irq: Always set IRQF_ONESHOT if no primary handler is specified

After reverting this commit, -rc3 boots fine.  I'm not sure where
exactly the problem is.  Maybe it's something in the omap code which is
broken and this patch causes the bug to show up?

What happens is that the booting process hangs after printing out this:

[...]

Any ideas what may be going wrong?
