CONFIG_PCI_MSI is disabled in kernel, still spurious interrupts are raised.
I tried with 3.1.10 kernel with adeos 3.1.10 patch with the same config file but no spurious interrupts are raised. adeos patches are working fine, problem only with ipipe series. why ppc_md.get_irq is reading FF when interrupt is raised (this is happening after patching the xenomai, without xenomai patch same kernel with same configuration is working fine).
