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.
