File kdump-fadump-umount.patch of Package kdump
From: Petr Tesarik <ptesarik@suse.cz> Subject: Clean up kdump mounts before continuing with FADUMP References: bsc#923790 Patch-mainline: v0.8.16 Git-commit: 7ed4ad5cb04a21b7561b674fd312b246fe705d51 Before pivoting the root, the initramfs content is wiped. This cannot be performed if there are still active mounts under /kdump, resulting in kernel panic. If the system is correctly configured for FADUMP, it will try to save a new dump from the panic after reboot, which fails the same way and so on...
