Comment (by ambroff):
I haven't had time to work on this since Saturday, but I'll collect more
info tomorrow or Wednesday.
My plan is:
1.) To try to reproduce with kvm
2.) To try reproducing with bare metal again now that I have more
instrumentation (I didn't have scheduler profiler in the build at all when
I first saw this)
3.) Try blacklisting mwait and intel_cstates
4.) Look into the lead waddlesplash found in the freebsd repo.
