The patch looks good, but i'll have to wait until it's pulled into Linus tree.

The bootlog (and crash) is attached. Asking on Tegra IRC channel, digetx found that this is caused by the IPMMU-VMSA driver which is always registered via initcall. Adding "initcall_blacklist=ipmmu_init" to the kernel parameters makes it boot fine. Maybe this buggy driver should be disabled in the config (or fixed somehow)?
