   This sounds very similar to what happens on my new Phenom X4 system.   
   In my case, it's SeaMonkey generally that causes the lockup, although   
   whether or not that's simply because it's the program I've been using   
   most often on that system or not, I don't know.  For me it seems to be   
   a pretty hard lockup in that nothing responds and I need to reboot.   
      
   For me, too, the "fix" is to either disable all but the first core in   
   the BIOS, or disable SMP.  (If I leave two cores running, the problem   
   happens less often than it does with four, but still happens.)   
      
   I've tried with both OS2APIC.PSD and ACPI.PSD, both exhibit the exact   
   same behaviour here.   
      
   Interestingly, however, I've observed the SAME behaviour under Windows XP   
   on the same box.  In this case, running on two cores instead of four    
   virtually eliminates the problem under Windows, although I have seen it    
   at least once.   
      
   This has led me to suspect a hardware problem rather than an OS one.   
   OTOH, if you have the same issue, maybe I'm wrong about that.
