some of the issues with tracking down such imprecise external aborts are
due to the fact that we only enable the signaling of those aborts on
entering the user-space. So the first schedule() crashes on the previous
dangling abort.

I'm carrying this patch locally to enable imprecise aborts much earlier
in the boot process. I think it has already been on the list some times,
but apparently it has fallen through the cracks. If you agree that this
is the right thing to do I can do a proper repost.

Regards,
Lucas
