isw attempt to access beyond end of device

Sun Apr 5 18:11:08 UTC 2009

Hey guys,

I'm having a problem on boot and at random times:

This then repeats a few times during boot, and onces or twice while
system is running.  The system becomes unresponsive when it happens.
Any ideas on how to fix this?  The system has been running, for the
most part, without other issues for a while.  I'd just like to get it
fixed if possible.
Thanks
