Message-ID: <007001d1ce27$17845550$468cfff0$@opengridcomputing.com> Date: Fri, 24 Jun 2016 09:45:46 -0500 From: "Steve Wise" <swise@...ngridcomputing.com> To: <linux-kernel@...r.kernel.org> Subject: vmcore not getting created on linux-4.7 I've been trying to get crash dumps working on linux-4.7 and haven't succeeded. The kdump kernel boots up and appears to be chugging along and then just reboots and never creates the vmcore, and fails to create the vmcore-dmesg.txt, though I've never seen that working on my nodes. Below is the tail of the boot. Any ideas?
