Subject: Help with decoding a NMI Watchdog interrupt on an Octeon
Date: Thu, 17 Jun 2010 17:03:02 -0400 [thread overview]
Message-ID: <4C1A8D86.60005@adax.com> (raw)
Hi, I need some tips on how to go about deciphering the following NMI dump.
This is from a 2.6.21.7 kernel that came with the Cavium Networks 1.8.1
toolchain.
Is there any way to get some kind of back trace from this, or just find
out which function it was in?
I have been playing around with objdump -x vmlinux but I cant zero in
on anything this way.
Thanks in advance,
Jan
