Hey: I am failing to install FC4-T1 on a Dell Optiplex GXpro with a Pentium Pro @ 200 MHz, 64MB of ECC RAM, 4.3GB drive, slow non-IDE non-bootable CD-ROM, and built-in 3c905 Ethernet adapter. This machine is known as Gemini on the LAN. Gemini is my main test machine and gets reinstalled constantly. It successfully installed FC1, FC2, and FC3 but barfs quickly on the installer for FC1-T4. Before I go off half-cocked to Bugzilla, let me ask you guys whether there's a known workaround and, if not, what information I should supply to Bugzilla. Here's what I do: 1. Download and check with sha1sum all the ISO files. All pass. 2. Expand them into an install tree. 3. Copy .../3.90/i386/os/isolinux/vmlinuz and initrd.img into Gemini's /boot. Modify /boot/grub/grub.conf to boot them. 4. Boot into the FC4-T1 installer. 5. Am prompted for language, keyboard, and install method. Select "English," "us" or "us-acentos," and "FTP." 6. Get IP address via DHCP fine, then point to correct FTP directory for network install. Download begins. If I leave everything alone, in about 15 seconds I get the following error repeated a few dozen times and then a hard lockup (after about one second of repeating errors): " <0>Kernel panic - not syncing: kernel/sched.c:313: spin_lock (kernel/sched.c:c04501c0) already locked by kernel/sched.c/313. (Not tainted)" 7. In an effort to troubleshoot, I press Alt-F3 to get some sort of progress indications. Stuff pages by quickly, but I'm able to see the "ext3" and "xfs" modules being loaded just before a LOT of stuff gets quickly thrown on-screen and these errors get repeated. Once the box locks I get nothing at all from it. So... can I work around this? Nothing found in Google, nothing found in Bugzilla, no clue here. Or should I post to Bugzilla as a new bug? If so, is there any additional diagnostic step to take so the bug filed is more useful? Help... :-) Thanks, -- Rodolfo J. Paiz <rpaiz@xxxxxxxxxxxxxx>
