To be clear: with the limits and without my patch you
can’t even boot right?

Is this with or without limits?
And is this with or without patch?

This is not a hang. This is a machine check.

I’m inclined to say that it’s best to remove the limits
altogether and just work with the default. If you need
different default, add them to your kernel configuration.
Set MAXTSIZ, DFLDSIZ, MAXDSIZ, DFLSSIZ and MAXSSIZ
Since you lower maxdsiz and maxssiz from 1G to 512M,
you can safely leave them as is (unless you tend to have
runaway processes :-)
You increase maxssiz from 256M to 512M, which you
probably want to keep doing to make sure you can run
the same set of processes as you do now.
At this point in time, the only fix I’m willing to make
is for the size of the array that holds relocations. If
it made things better, I’ll commit it. If it didn’t, then
I’m not going to commit it.
Anything more involved will take more time than I’m
willing to put into ia64 at this time...
