VME interrupts are only received if: 1) ACPI is disabled either in the BIOS or using acpi=off on the kernel command line and 2) APIC is disabled either in the BIOS or using noapic on the kernel command line Reproducible: Always Steps to Reproduce: 1. Enable ACPI and APIC in the BIOS 2. Reboot 3. Load VME device driver(s) 4. Reboot with acpi=off and noapic on kernel command line 5. Load VME device driver(s) 6. Disable ACPI and APIC in the BIOS 7. Reboot 8. Load VME device driver(s) Actual Results: After step 3 above, interrupts from the VME backplane are not received After steps 5 and 8 interrupts from the VME backplane are received Expected Results: Interrupts should be received if ACPI and APIC are enabled. The relevant processors are described in http://www.xembedded.com/content/vme/processors/xvme-6200.php and http://www.xembedded.com/content/vme/processors/xvme-690.php Please note that the XVME-690 is on 11.1 and APIC is not applicable.
