Re: ThinkPad R51 creeping segmentation faults

I finally got back to this ThinkPad R51 stability problem and was able to definitively assign blame to a defective (at least in this box) memory module. Defective memory was suggested on list as a probable cause, so thank you. I first used the "mem=1G" kernel boot parameter to limit memory used

nstall emacs24 because I have some confidence that the problem won't occur with emacs24, just as it doesn't occur with my built emacs23. But I'll still have the problem so I'm going to keep the native emacs23 for a bit longer to see if I can come up with a more general solutio

I recently replaced the hard disk in my ThinkPad R51 with a solid state drive and when I did so I installed Debian Wheezy LXDE updated with a 3.16 kernel as one of the boot options. I really am pleased with how the system looks and acts except for a curious instability that occurs increasingly
