Ah. So it's the UIC support that likely breaks. Could you try this patch? diff --git a/arch/powerpc/sysdev/uic.c b/arch/powerpc/sysdev/uic.c index dd40f64..4eff1ab 100644 --- a/arch/powerpc/sysdev/uic.c +++ b/arch/powerpc/sysdev/uic.c @@ -111,7 +111,6 @@ static void uic_mask_ack_irq(unsigned int virq) sr = 1 << (31-src); spin_lock_irqsave(&uic->lock, flags); - ipipe_irq_lock(virq); er = mfdcr(uic->dcrbase + UIC_ER); er &= ~sr; mtdcr(uic->dcrbase + UIC_ER, er); In case it is not enough, try removing all the ipipe_irq_lock/unlock calls from arch/powerpc/sysdev/uic.c. If that works eventually, I'll sort the mess out later. I started with the DENX-v2.6.25-stable branch from the > DENX linux-2.6-denx git tree, then applied Xenomai-2.4.4 using its > install script.
