Kernel and Initialization Issues

Q

This problem has been fixed in the 2.6.17 kernel.org kernel.

If you try to load the InfiniPath driver on a kernel that InfiniPath software does not 
support, the load fails. Error messages similar to this appear: 

modprobe: error inserting

’/lib/modules/2.6.3-1.1659-smp/kernel/drivers/infiniband/hw/ipath/

ib_ipath.ko’: -1 Invalid module format

To correct this, install one of the appropriate supported Linux kernel versions as 
listed in 

, then reload the driver. 

The InfiniPath driver will not be able to configure the InfiniPath link to a usable state 
unless interrupts are working. Check for this with the commands:

$ grep ib_ipath /proc/interrupts

Normal output will like similar to this:

CPU0       CPU1

0:   22577705   22968429    IO-APIC-edge  timer

4:        415        774    IO-APIC-edge  serial

LOC:   45540410   45540372

ERR:          0

MIS:          0 

If there is no output at all, driver initialization has failed. For further information on 
driver problems, see 

However, if the output appears similar to one of these lines, then interrupts are not 
being delivered to the driver:

66:  0 0 PCI-MSI ib_ipath

185:

0

0

IO-APIC-level

ib_ipath

The output you see may vary depending on board type, distribution, or 
update level.
