Tony,
The latest tree does not boot on Altix.
Looks like low bootmem is broken.
"low bootmem alloc of 128 bytes failed!"
The tree was pulled down using:
cg-clone git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6.git test
Built using arch/ia64/configs/sn2_defconfig (default settings).
I can look closer later tonight.
The output:
