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..
