C – Troubleshooting

Kernel and Initialization Issues

A zero count in all CPU columns means that no interrupts have been delivered to the processor.

Possible causes are:

■Booting the linux kernel with ACPI (Advanced Configuration and Power Interface) disabled on the boot command line, or in the BIOS configuration

■Other infinipath initialization failures

To check if the kernel was booted with the "noacpi" or "pci=noacpi" options, use this command:

If output is displayed, fix your kernel boot command line so that ACPI is enabled. This can be set in various ways, depending on your distribution. If no output is displayed, check to be sure that ACPI is enabled in your BIOS settings.

To track down other initialization failures, see appendix C.4.6.

The program ipath_checkout can also help flag these kinds of problems. See appendix C.9.8 for more information.
