I've seen this float through this list or that about 30 different times in the past. Not once has it ever been a kernel or driver issue. In *every* case it has been either RAM, cache, or CPU. Check the CPU fan, check the cache (if it isn't part of the CPU) and check your RAM. -- Doug Ledford Opinions expressed are my own, but they should be everybody's.
