Date: Mon, 22 Dec 2008 09:05:58 +1300 From: "Keith Chew" <keith.chew@...il.com> To: linux-kernel <linux-kernel@...r.kernel.org> Subject: bug or hardware memory error? Hi I have been experiencing some occasional errors in bttv using kernel 2.6.20.1, we suspect could either be: - hardware memory problem - software memory problem - IRQ conflict with wireless WIFI driver (zd1211 module below) Can someone assist by looking at this stack trace: -------------------------------------------------------- Dec 20 18:28:00 localhost kernel: BUG: unable to handle kernel
