I actually haven't looked at the NMI branch yet. I'm still trying to
figure out why the ftrace one would lockup. I'll try another box to see
if that one also locks up on tip/master with your config.

Did you just merge in the branches, or do you see the same problem if
you test the head of the branch itself?

In other words, did the branch have the issue, or is the branch causing
an issue with something already in tip?

BTW, I did a make oldconfig with the config you gave me, and the result
is a bit different:

diffconfig your-config .config

-BOOTPARAM_SUPPORT_NOT_WANTED y
-BROKEN_BOOT_ALLOWED2 y
-BROKEN_BOOT_ALLOWED3 y
-BROKEN_BOOT_ALLOWED4 y
-BROKEN_BOOT_DISALLOWED y

-BROKEN_BOOT_TITAN n
-FORCE_MINIMAL_CONFIG y
-FORCE_MINIMAL_CONFIG_64 y
-FORCE_MINIMAL_CONFIG_PHYS y
-FORCE_SUCCESSFUL_BUILD y
-SMP_SUPPORT y

Was the config based off of tip/master? I'm a missing a branch?

Thanks,
