Yes, the machine is nearly unusable when booting with SMP (I think). I
booted it with -1 -2 last night and it's still running this morning.
All it has done is a few cvs checkouts and updates though.

Another detail, not sure if it's related:

I have a wm network adapter and performance with it was horrible, I
was getting +4000ms pings to my gateway on a wired gigabit network. I
switched to USB3 gigabit adapter (cdce) and things are working

I am checking out -current right now and I will build a kernel and report back.

There are no PRs about this recently, I'm willing to open one for this
panic if this will help.
