I don't think so. I just tried to reproduce the problem here with openSUSE 11.1 (I have no SLES). In my case, I also got the "killed", but it was too less memory. I changed the reservation to be 256 MiB for the crashkernel, and now it works. I did in the shell I got in the kexec environment: % ln -s root/boot/vmlinux-2.6.27.7-9-pae . % ln -s root/usr/lib/debug/boot/vmlinux-2.6.27.7-9-pae.debug . % echo bt > cmdlist % root/usr/bin/crash vmlinux-2.6.27.7-9-pae /proc/vmcore -i cmdlist With this, I got a backtrace. I also get the libthread_db warning, but it was harmless. BTW: Did you try to set LD_LIBRARY_PATH? Maybe it's necessary so that dlopen() finds the lib. But I didn't investigate ... HTH.
