Description of problem: PAE enabled Kernel does not boot since it cannot find initrd on a machine with 4GB of memory. Version-Release number of selected component (if applicable): kernel-2.6.18-1.2849.fc6PAE grub-0.97-13 How reproducible: Always Steps to Reproduce: 1. Attempt to boot kernel on system with > 4 GB, with initrd, from GRUB 2. 3. Actual results: Kernel does not find initrd image (initramfs) and panics since it cannot find init. Additional info: The machine has 4 GB of memory, but the upper 2 GB are mapped above the 4 GB barrier. Adding "mem=4096M" to the kernel command line overcomes the problems, but disables the upper 2GB of memory.

(This is a mass-update to all current FC6 kernel bugs in NEW state) Hello, I'm reviewing this bug list as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained. Please attempt to reproduce this bug with a current version of Fedora (presently Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a few days if there is no further information lodged. Thanks for using Fedora!
Per the previous comment in this bug, I am closing it as INSUFFICIENT_DATA, since no information has been lodged for over 30 days. Please re-open this bug or file a new one if you can provide the requested data, and thanks for filing the original report!
