I did this on my machine as well, it's a i386 single core processor running a single processor kernel. I ran this stress test several times, no panic. Your panic trace also indicates complications with uvm's page fault handler and an MP locking mechanism involved. Therefore, could you try bsd.sp and do the stress testing again? Is it running well now? Norman.
