512MB to 1GB RAM upgrade makes system run slower
I have a Pentium M laptop (Chinese clone) which is just over a year old. When I purchased it, it had 512MB RAM. This afternoon I added a second 512MB SIMM. The BIOS recognized it, but to my great astonishment it made my system run like cold molasses; it took about ten minutes to boot Ubuntu (Breezy). I have been told it may have something to do with "high memory", but all the Google searches I have done seem to indicate that this was a issue with earlier =< 2.4 kernels. Does anyone know anything more about this?
