With the SP2 default kernel, it should work. At lest /proc/vmcore should have a normal size. Can you set KDUMP_IMMEDIATE_REBOOT to "no", then log in in the serial console and execute # ls -l /proc/vmcore For 2.6.27 kernel on IA64, you have to update kexec-tools. I don't know the exact version when the change was included, but 2.0.0 is safe. :) Bernhard -- Bernhard Walle, SUSE LINUX Products GmbH, Architecture Development -- To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
