We want to update to a 2.6 kernel, recent build tools, and saner system

supported, I have not found any info on whether anybody is still running
Linux on it and what combination of software they are using. Any idea?
Is there a combination of software versions that are known to work on this
I have used crosstool 0.43 to build:
http://www.linux-mips.org/wiki/Toolchains recommends binutils 2.16.1 and
gcc 3.4.4, but I believe your choice is also ok for 32-bit systems.
I will try that combination also.
I wish that there were more of a boot log of which to speak. The
following is a complete boot log:
Hard to tell from so little information, it would help to see the whole

All messages before the exception are from PMON. I am booting via TFTP.
I also tried writing the kernel to flash and booting from that, but that
I checked the other serial port on the device, but it is not showing any
kernel messages either. The normal boot console is ttyS1. I tried
setting the kernel parameters and the default parameters (from the
kernel build config) to "console=ttyS1", but that made no difference.
Regardless, I would think that the kernel knows where to send messages
because I am seeing the exception dump on ttyS1.
Further, the exception gets printed immediately after "Image Length =
3424394 (0x34408a)." The exception happens so soon that I doubt that the
kernel does very much beforehand.
