Both are kernels of SLES11 xon x86_64. The first one is the latest you can get for SLES11 SP2. In openSUSE 12.1 (kernel 3.1.10) it's also still missing. Anyway, it's nice to see that others also thought this feature is useful. Thanks & best regards, Ulrich >>> Borislav Petkov schrieb am 14.08.2012 um 15:12 in Nachricht <20120814131211.GA25921@x1.osrc.amd.com>: > On Tue, Aug 14, 2012 at 02:35:40PM +0200, Ulrich Windl wrote: > > Hi! > > > > After several reboots due to memory errors after excellent power-saving of > Linux on a HP DL380G7 with Intel Xeon 5650 processors (all in on memory > bank), I found out the errate "BD104" and "BD123".
