I have to go, but I took a quick look at your one dump:

This is a panic while servicing a page fault.  Usually when I see something like this, I have to ask if your HW is okay.  ("fmadm faulty" show anything?)

Beyond that, I'll need to dig deeper, but I can't now.  Just wanted to let you know the stuff on the surface, at least.

Thanks for sharing the dump!
