Subject: Strange soft lockup detected message
Date: Thu, 3 May 2007 16:31:43 -0400 [thread overview]
Message-ID: <20070503203143.GA8753@csclub.uwaterloo.ca> (raw)
I have had this happen a few times recently and was wondering if anyone
has an idea what could be going on:
BUG: soft lockup detected on CPU#0!

[<00005791>] 0x5791
This is on a system running a Geode LX at 500MHz, using 2.6.18 based
kernel (specifically a slightly modified debian 4.0 Etch kernel).
I am really wondering where do I go looking for the cause of this. The
same kernel running on a Geode SC1200 (GX1) does not appear to do this.
If I knew what the error meant I would have a better idea how to debug
it and fix it.
