The problem persists for me too. It's the first time I installed a 64 bit kernel (intrepid, last time updated a few minutes ago), running on my intel Core 2 Quad Q6600. I have 8 GB of RAM installed, but only 3.2 GB are recognized.
Output asked for above gives me: MemTotal: 3347080 kB MemFree: 1688248 kB Buffers: 258660 kB Cached: 718196 kB SwapCached: 0 kB Active: 757424 kB Inactive: 647488 kB SwapTotal: 7815612 kB SwapFree: 7815612 kB Dirty: 316 kB Writeback: 0 kB AnonPages: 428096 kB Mapped: 102060 kB Slab: 153872 kB SReclaimable: 84232 kB SUnreclaim: 69640 kB PageTables: 15728 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 9489152 kB Committed_AS: 833572 kB VmallocTotal: 34359738367 kB VmallocUsed: 316320 kB VmallocChunk: 34359421435 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 130752 kB DirectMap2M: 3276800 kB -- Trouble viewing beyond 3GB of available 4GB memory using 64bit kernel https://bugs.launchpad.net/bugs/114258 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
