Bug 707634

Description of problem:

One of my servers is unable to boot F15 vmlinuz via grub, as described in sections 11.1 and 11.2 of the installation guide.

Version-Release number of selected component (if applicable):

Fedora 15

How reproducible:

Always

Steps to Reproduce:

Copied F15 vmlinuz and initrd.img off the DVD


[root@octopus ~]# cd /boot
[root@octopus boot]# ls -al pxeboot
total 100548
drwxr-xr-x. 2 root root     1024 May 25 07:29 .
dr-xr-xr-x. 7 root root     3072 May 25 01:59 ..
-rw-r--r--. 1 root root 98678344 May 25 07:04 initrd.img
-rwxr-xr-x. 1 root root  3867920 May 25 07:04 vmlinuz
[root@octopus boot]# sha256sum pxeboot/*

[root@octopus boot]# tail grub/menu.lst

[ ... ]

title update
	root (hd0,0)
	kernel /pxeboot/vmlinuz
	initrd /pxeboot/initrd.img

Actual results:

Making this selection from the grub menu results in a blank screen with a blinking cursor, no error message and no activity. System only responds to a three-fingered salute.

Expected results:

Boot F15 anaconda.

Additional info:

Appears to be hardware specific, I was able to start the same vmlinuz on another machine. I was able to start the same vmlinuz on this machine via a network boot.

To make sure I wasn't imagining things, I installed F14's vmlinuz and initrd.img into /boot/pxeboot, on the same machine, and was able to boot them using the same grub config.

Results:

grub -> F14 vmlinuz: boots
grub -> F15 vmlinuz: does not boot
network -> F15 vmlinuz: boots
grub -> F15 vmlinuz, different hardware: boots

vmlinuz appears to fail very early in the boot process, before any of the usual boot messages begin to scroll.
