I'm commenting here in case what I say might have an impact on whether this bug is a duplicate of bug 74179 or not. I'm running the Jaunty RC (2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux) on a desktop with 4 GB. The BIOS reports 4GB on startup, but /proc/meminfo says it sees only 2838352 kB (2.75 GB). I tried the Grub patch suggested by Andrew, but it didn't change anything for me -- Ubuntu still sees only 2.75 GB. Since the Grub patch was proposed in the context of the "Xen-PAE kernel", I'm going to guess that the kernel in this case was already PAE-enabled. So perhaps the reason the Grub patch did nothing for me is because I'm running a vanilla "desktop" system (and many people have said that the desktop kernel doesn't have PAE enabled). But I just wanted to put it on record that, in my case at least, the Grub patch did *NOT* give me access to any extra memory, and the problem still remains as best I can tell. -- CONFIG_HIMEM4G does not allow 4gb of ram in kernel https://bugs.launchpad.net/bugs/189269 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
