Hi Philippe,
I pulled your latest commit on the "next" branch (5e681f841fc3), I built it
with the normal debug configuration parameters enabled, and ran my test case
against it. I appear to be seeing the same behavior as before. No crashing,
but many threads that are boosted infinitely. I did get a kernel splat
again; it looks oddly similar to the one I sent previously with the old
kernel.... Doesn't make much sense to me. I verified I have the latest
commit checked out and built.
Thanks,
Russell
