Linux crash when big application executing on PPC405GP board

[Jikun Sun]

Hi,

Board: CSB272 IBM PPC405GP
Linux kernel version: 2.4.17
Linux kernel can boot nfs root filesystem on the board. Shell works
correctly.
However the system will oops when execute big applications, such as
copying a file which is larger than 2MBytes.
The following is ksymoops:

The size of vmlinux.srec is 2.076Mbytes.
root@192.9.200.145:/# cp vmlinux.srec  vmlinux.srec.bak

Where did you get your kernel?
What compiler did you use to build it?

Which version, Montavista Linux 2.1?
Are you using their software unmodified, or have you changed anything?
I assume this is the unsupported preview edition,
otherwise you'd be on the phone to Montavista?

What does ppc_405-gcc --version say?
