[openib-general] Problem Building OpenIB on 2.6.12 kernel

You may run into other problems, because now that 2.6.13 is out, the
OpenIB subversion tree will support 2.6.13 instead of 2.6.12.

    Don> When we add IPoIB, we get:
 
    Don> drivers/infiniband/ulp/ipoib/ipoib_main.c:478: error:

Strange, I've never seen that error.  Can you figure out how
<linux/namei.h> is getting included while building ipoib_main.c?

    Don> Also, will the GEN2 stack work with a 64K page size kernel?
    Don> If not, is there a plan to make it work?

I don't think anyone has tested it, but if you have new enough HCA
firmware (>= 3.3.3 for PCI-X HCAs), it should work.  If it doesn't
work I'd be interested in hearing about it.
