Ohh, that one.
Can you instrument this piece of code:
413 if (request_irq(irq, acpi_irq, IRQF_SHARED, "acpi", acpi_irq)) {
414 printk(KERN_ERR PREFIX "SCI (IRQ%d) allocation failed\n", irq);
415 return AE_NOT_ACQUIRED;
416 }
To print out the return value of request_irq and see what it returns?
If it is EINVAL, instrument the 'request_irq' around its 'return
-EINVAL' to see which one fails.
Also can you provide the full serial output of the failing system
including Xen output?
