From: Peter Zijlstra To: Ingo Molnar Cc: LKML Content-Type: text/plain Date: Sat, 09 Jul 2005 16:29:26 +0200 Message-Id: <1120919366.14404.5.camel@twins> Mime-Version: 1.0 X-Mailer: Evolution 2.2.0 Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi Ingo, I got the following BUG while playing a nice tune with xmms. Shortly after the BUG the machine froze hard and I had to reach over and press the reset button. PS. there is a simple compile error in 51-18 when CONFIG_DEBUG_STACKOVERFLOW is undefined. BUG: xmms:2200 RT task yield()-ing!
