 From what I saw, 'not stripped' doesn't mean it has the .debug_info 
section. After I compiled a kernel with '-g' flag and feed that to 
crash, that error message went away. You can use 'readelf' to check the 
existence of .debug_info section. So far the non-SMP SLES kernels seem 
to work fine with crash once you build the kernel with '-g'. However, 
there seems to be  some problems with crash and SMP SLES kernels... I'm 
having a discussion with Dave Anderson in another thread on that which 
you can check out if you are interested.

Later,
