So forgive if memory of the bugs in that kernel is fading. I think the one you're seeing was was caused by memory prefetching beyond the end of memory. The easy fix is to disable prefetching. See a modern memcpy for how to do that. There are several other interesting issues hidden in 2.6.8 so I think you really should upgrade. Ralf
