From ff6b8ea68f4b7353f88b97024f28127e2148aa00 Mon Sep 17 00:00:00 2001 From: Michael Holzheu Date: Wed, 20 Sep 2006 15:58:49 +0200 Subject: [S390] ipl/dump on panic. It is now possible to specify a ccw/fcp dump device which is used to automatically create a system dump in case of a kernel panic. The dump device can be configured under /sys/firmware/dump. In addition it is now possible to specify a ccw/fcp device which is used for the next reboot of Linux. The reipl device can be configured under /sys/firmware/reipl.
