Clearly not, it doesn't disable anything (in case it's not obvious, I'm looking for a real fix, not for a work-around). I managed to put my hands on a previously failing SMP box with PCI_MSI enabled, and 1.5-00 does fix the issue there. So the current issue we are discussing must be different. Could you redo test #1 disabling Xenomai, and dump /proc/interrupts on your box?
