on the intel platform, with the test input set, all of cpu2006 integer tests pass, except for astar. astar dies with a panic and page fault. [m5PageFault:build/X86/arch/x86/pseudo_inst.cc, line 85] on the amd platform, all of the tests I tried fail to complete. time continues to advance, but instructions are not completing. I am not sure what to do, I need the Intel platform code, but we should not break the AMD side. Are there any AMD folks I can work with to figure out how to get both sides working? - mike ----------------------------------------------------------- This is an automatically generated e-mail.
