I don't think you need to worry about this. It seems to be working as intended. Do you have any reason to think it's causing a problem?
The following line in the log shows linux is working around this BIOS issue. [ 0.004000] This costs you 64 MB of RAM [ 0.004000] Mapping aperture over 65536 KB of RAM @ 20000000 If you can change the BIOS settings to avoid wasting this 64MB of RAM, then great. But it looks like you have over 4GB, so it's peanuts in relative terms :-). ** Changed in: linux (Ubuntu) Status: New => Incomplete -- "Aperture beyond 4GB" on startup https://bugs.launchpad.net/bugs/330977 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
