Hello,

I've got an IP27 up and running with 2.6.11 from CVS, and it seems
pretty robust.  I cross-compiled from x86 with the handy-dandy RPMS
kindly provided by Maciej (see "Toolchains" in the wiki).  I used:

binutils-mips64-linux-2.15-1
gcc-mips64-linux-3.4.3-1

The ip27 defconfigs produce a workable system.

Previous 2.6.11-rc* CVS versions were broken on ip27.

HOWEVER, I have only been able to get my Origin 200 to work with
one node.  If I hook up the other node, I get lots of woe (woe enclosed
below).  If you're using more than one node, I suggest unhooking the
others to start off with..

If you can't xcompile, I can send you my vmlinux + modules..
