Background info on my X60: I've some heat issues: After disassembling
and reassembling it a lot, it got less efficient in heat-cooling.
So I'll try to fix it by putting back some thermal paste, as soon as
possible.

That said, I can reproduce the freeze when making cpu-intensive work.
I use parabola with linux-libre (I don't remember the exact version),
and I didn't try linux-libre-lts recently.

   You probably  want to identify which commit broke it, you'll need to
   either test fast, or test few revisions.

   Test fast: try to find how to reproduce the problem faster, then you
   can bisect with git-bisect.

   Test fewer revisions: try to narrow it down more using
   older parabola linux-libre kernels.

   An automated way to do that could be done thanks to the watchdog(s).
