Note, kdump will not work if the issue is a hardware reset. So if you do install kdump and test kdump and verify it works and then when it crashes you do not get a kdump then that points to a hardware issue. On one of my other systems, on reboot after a hw crash it detected that there were prior MCE errors and noted that on the boot back up, so it may be worth checking dmesg after reboot to see if MCE's were reported.
