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 to the lowest addressed 1GB part out of two. When that 
configuration proved stable, I then swapped the memory module in the 
expansion bay, assumed higher address, with one in another laptop that I 
have. That configuration proved stable as well. So problem solved for 
the ThinkPad R51.

Both modules mentioned are by Crucial. Thus far, the  module that didn't 
function reliably in the ThinkPad R51 seems to have no problems in my 
Compaq NX6110. Of course I'm still tracking that module and have a 
couple of backup modules on order. The modules on order are not by Crucial.
