From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040706 Firefox/0.9.1 Description of problem: Hello I own a DELL Optiplex gx150 and experienced a really weird error on this machine: If I boot the machine, it will hang directly after the grub menu. If I reset the machine in the Grub menu via ctrl+alt+del it will boot up ok afterwards. It also boots without problems if I add acpi=off to the kernel arguments. I wouldn't have searched the problem in Grub but in the BIOS or the kernel, but the amazing thing is: Updating to grub-0.95-2 from Fedora Core 3 Test 1 fixes it. Version-Release number of selected component (if applicable): grub-0.94-5 How reproducible: Always Steps to Reproduce: 1. Install Fedora Core 2 on a Dell Optiplex gx150 2. Power down 3. Boot up Actual Results: The screen goes blank and the machine hangs right after the grub boot menu. Expected Results: It should boot up. Additional info: The machine contains an Intel i815 chipset, BIOS is A 10, the newest available.
It's probably actually a BIOS bug that gets tickled a little bit differently with some of the changes in grub 0.95. Unfortunately, doing an update of the grub package isn't practical (it's more likely to trigger new problems and hard to get the change applied for people who do want it). So fix is in rawhide, that should be usable without any problems by people on FC2 hitting this.
Yes, my main intention for filing the bug report was giving a chance to someone who has the same problem to find the solution. As a sidenote: One has to upgrade fedora-logos as well. (Grub 0.95 requires system-logos which the fedora-logos package from Core 2 doesn't provide).
