A long time ago, there was a bug somewhere that only affected boards with 512MB of memory with RM7000 processors. Apparently, there were problems in the cache-managment code causing a problem working with memory near the end of kseg0. I don't recall all the details -- by the time I got to looking at it the first time, someone already had a fix. I was told this was fixed... but I'm seeing some symptoms that this was not fixed. Does anyone actually recall if this was fixed or not? If it was, I need to look elsewhere. But, if it wasn't actually fixed.... Matt -- Matthew D.
