Hi, I tried crash 5.0.3 for linux 2.6.34 (x86_64) and faced the problem about per-cpu data symbol naming, which is described in ChangeLog as it's already fixed. I observed to fix the problem and found the following fix for x86_64_verify_symbol() in x86_64.c helped me. I'm not sure whether the fix is correct or not, but it would be help for correct fix.
