In 2054_FC5 and 2054_FC5kdump, the config files have: CONFIG_KPROBES=3Dy ... CONFIG_DEBUG_INFO=3Dy Whereas in 2054_FC5xen0 and 2054_xenU, the config files have: # CONFIG_KPROBES is not set ... with no mention of CONFIG_DEBUG_INFO. This might explain the missing dwarf info in the kernel-debuginfo package. And of course for SystemTap we need CONFIG_KPROBES=3Dy. Josh
