Kernel crash on yosemite

This is my configuration:
~ yosemite board with RM9000 chip revision 1.1
~ BusyBox 1.0
~ Kernel 2.6.8.1

When I try to copy a large file (~ 3,5 Mb) within the NFS file system the kernel crashs without any output on the console.
It could be a problem with the titan_ge driver, but I have no idee how to solve the problem.

What can I do?

There have been various fixes to the network driver since then so I recommend you upgrade your kernel. One problem you're going to encounter with recent kernels is that they only support the Titan 1.2 part which I think are the ones in volume production.

However, adding support for Titan 1.0 and 1.1 in the GE driver should be fairly straight forward.

True, the CVS log should provide reasonable information about that. What can't be sanely retrofitted is SMP for < 1.2.

I completely agree. In any case, I dont think the CVS sources ever supported SMP for Titan < 1.2, correct?

No, that would have either meant taking a heavy performance penalty or hacking mm in very ugly ways.

And due to the probably low numbers of
the early silicon and the availability of later revisions the reason for such hacks was low anyway.

How would I not know this? After all, I was the one who actually put this code together to get SMP to work on Titan 1.0 and 1.1, remember? ;) And you are right, there is no reason to put such hacks.

I'm sorry, but all the discussion on this thread did'n help me to solve my problem. Since more than a month I'm waitig to get a yosemite board with 1.2 version. This still stops my development, when I can't use the yosemite with 1.1 version.

In another therad we discuss to create a patch (slowpath) for the titan version 1.1. the patch I apply to the the newer kernel sources (2.6.11.rc1) but, I have the same problems. So I think the problem could be the slowpath thing.

Have anybody an idee how to figure out what could be the problem when I make "cp foo foo1" (foo is a lage file ~3,5 Mb)?
