Sorry, I just forgot it. Here it is. And yes, the values are larger in the end. And also our /boot/System.map on IA64 has zero-prefixes. The map.4 file is generated by lkcd, and they simply don't use the zero prefixes. Which should not matter, IMO. So I vote for applying the attached patch. > I'd never seen those types of __crc_ absolutes, probably because > they don't show up in our kernels.

Hm ..., I also don't understand why the /boot/System.map of the same kernel isn't identical to the map.4 file generated by klcd. In fact, map.4 is missing symbol and gdb fails to load. But even with the /boot/System.map of the right kernel, it doesn't work (i.e. backtrace is complete garbage). But first I'll fix the header format which _is_ different in crash and our SLES9 kernel (and klcdutils), and if it then doesn't work I'll come back to the system maps. Thanks for your help!
