The file sizes of /sbin/sysctl are different. I don't have time to rebuild the ALPHA5 system right now for further debugging, but thought this should get reported before the next RE event for 10.0.   
 
 To fix the problem, we need to see details of crash dump. At least
 the panic screen, but better to have a kernel dump and backtrace
 from it.
 
 The problem isn't global, e.g. on my boxes sysctl -a runs fine.
 
 Something is special in your environment, so we need your help
 to find the problem.
