Otherwise, I found the size of dump file(dump-incomplete) is about 25M, but my memory is 4G. The more log can be seen in the attachment: crash.log but when I analyze the dump file using command: crash -d8 vmlinux dumpfileĬrash: seek error: kernel virtual address: c1625ccc type: "cpu_possible_mask" I configured the kernel compile para according to the kdump-tutorial, and get dump file in /var/crash/ through echo c > /proc/sysrq-trigger. I am using KDUMP tools( version: 2.0.4) to capture kernel panic information.
