Comment 269 for bug 131094

The latest Lucid kernel ("2.6.32-12.16", 64bit) seems to have fixed this longstanding problem for me. Also, for this reason or another during the update, the initial RAM usage appeared to go down a good ~64MB. Before, this machine was mysteriously less usable than an otherwise older and slower one (even after accounting for this having half the RAM). Of course, this bug is fairly general, and could have a few potential causes, so my case may not apply to all who reported this one.
