Subject: How to debug random bus errors?
Date: Fri, 22 Sep 2006 11:11:14 -0600	[thread overview]
Message-ID: <ef15fm$uhs$1@sea.gmane.org> (raw)

We're seeing programs die with "bus error" (SIGBUS) randomly on a dual 
processor Opteron machine.  I've run memtest86+ and cpuburn stress tests 
with no failure.  gdb on a core file seems uninteresting.  Is there some 
way to trace the kernel to try to get more insight?

Thanks!
