Does the behavior still occur on modern versions of Ubuntu and/or modern kernels? It's much more likely your mobo reserving space for hardware addressing or a kernel bug. If 'free' command reports the same, then this bug should be assigned to a different package.
Marking Incomplete until someone confirms it's still an issue and confirms what free command reports. ** Changed in: sysinfo (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/675062 Title: Sysinfo for 1024mb ram shows 1001 mb ram To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sysinfo/+bug/675062/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
