From e3d3683d1402c1737687cb698451d545f57c32a7 Mon Sep 17 00:00:00 2001 From: Michael Holzheu Date: Mon, 22 Oct 2007 12:52:43 +0200 Subject: [S390] kernel: Fix dump on panic for DASDs under LPAR. Currently the ccw method is used to ipl the DASD dump record under LPAR. This mechanism is not reliable, which can cause dump failures. This fix now uses the diag 308 ipl method for all machines, which have diag308 subcode 5 and 4 support.
