Try "vga=ask" and see if it prompts for a video mode. It does. Hitting the spacebar to continue, it reboots as usual. I guess that confirms that we're in kernel-space at that point?

No, but at least the kernel got loaded into memory and the setup code was run. There were some bugs recently fixed in there, so maybe we should wait and confirm the bug is still in 2.6.23-rc1-git1, which is building now. Will, did you try -rc3-git1? Still trying to build an installer image with that kernel. Will update when I've tested. kernel-2.6.23-0.47.rc1.git1.fc8 still reboots at startup. I don't see rc3-git1 anywhere in koji - did you mean rc1-git3? (In reply to comment #6) > kernel-2.6.23-0.47.rc1.git1.fc8 still reboots at startup. I don't see rc3-git1 > anywhere in koji - did you mean rc1-git3? Yes, but that's probably not going to help. Can you try the boot disk on a few more machines to see if this is a general problem? (I booted vanilla 2.6.23-rc1-git3 from floppy on a Dell 490 and that works.) Sorry, I should have noted this above - I can *only* make this bug manifest when booting from CD with ISOLINUX. The systems boot happily with GRUB loading the kernel from /boot. So I'm not sure if floppy-booting would trigger it. I'll try some non-dell machines and see whether I can narrow the problem further. Boot of live CD rawhide-20070725 on i386 fails on Dell 400SC 1) Boot i386 gnome on Dell 400SC 2) Get grub screen 3) Select boot from image 4) initrd loads 5) "Ready" message 5) machine reboots itself Chuck, I finally got a working iso using the most recent rawhide kernel (with debugging printks) - here's the output. ISOLINUX 3.36 2007-02-10 Copyright (C) 1994-2007 H. Peter Anvin Loading linux...................................Ready. query_mca query_ist query_apm_bios query_edd go_to_protected_mode realmode_switch_hook move_kernel_around enable_a20 reset_coprocessor mask_all_interrupts transition to PM... At that point, the cursor moves to the top left of the screen, prints a '.', and the system hangs. my Toshiba Tecra S3 laptop does exactly the same, so it is not Dell-related. (In reply to comment #10) > Chuck, I finally got a working iso using the most recent rawhide kernel (with > debugging printks) - here's the output. Are there instructions available for building one of our boot CDs? It's a little complicated - you can follow the guide for building ISOs here: http://fedoraproject.org/wiki/QA/BuildingISOs Once you've got the configs set up, pungi -GB should create boot images. On the other hand, 'make isoimage' in the kernel source dir works as well - I've confirmed the failure using an isoimage built that way. That's how I got the debugging output from comment #10. I think the culprit has been found! Booting with 'edd=off' works for my test machine. The following patch is proposed to fix the problem in the kernel: http://www.kernel.org/pub/linux/kernel/people/hpa/x86setup-edd.patch Patch is in rawhide, building now. |
