Description of problem:
A number of problems is preventing me to boot this version (after
figuring out the mkinitrd problem!):
1. I get a kernel panic when mounting the following device:
/dev/vg01/lv_data /data ext3 defaults 1 2
from fstab. The device file is there. I am not sure what this is for since it
came from Dell as part of the preinstalled linux. It seems to be empty.
2. The /boot/vmlinux-version points to the wrong location /usr/lib/debig/lib/modules/vmlinux-version... which does not exist!
Also, /lib/modules/kernel-version/vmlinux* does not exits either!
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install kernel-2.6.0-1.2
Actual Results: kernel panic
Expected Results: system start
the vmlinuX file is only useful if you want to run gdb on the kernel
and is HUGE so we stuck it in the debuginfo rpm only (99.9999% of the
people don't need it and it'd be a waste of space and bandwidth for them)
Ok...I have /boot and / as different partitions. The boot comes all the
way to before calling init and gives an error saying unable to mount
root partition, and than it panics because it cannot find init. The 2.4
kernel works fine with this setting. Here is my grub.conf file:
title Fedora Core (2.6.0-1.21smp)
kernel /vmlinuz-2.6.0-1.21smp ro root=/dev/sda5 hdc=ide-scsi
title Fedora Core (2.4.22-1.2129.nptlsmp)
kernel /vmlinuz-2.4.22-1.2129.nptlsmp ro root=/dev/sda5 hdc=ide-scsi

Trace dump from kernel panic
I get the <a
kernel panic booting 2.6.0-1.21 (i686) on my Vaio Z1MP (Pentium-M 1.3
GHz, 768MB RAM, 40GB HDD, running Fedora Core 1 with updated mkinitrd
and selinux packages). I recall running 2.6.0 test kernels just fine a
few months ago, and the exact same panic is reproducible when booting
with pci=noacpi and acpi=off
Downloading -1.23 now to see if this is fixed.
It seems Dave enabled PNPBIOS by mistake....
try booting with pnpbios=off on the commandline (and you need to
remove the ide-scsi part as well for 2.6...)
PNPBIOS was the culprit, thanks. I *knew* I was missing something
after trying acpi= and pci=, but could not remember what. Same problem
with -1.23 too - and as for ide-scsi, I thought it's not even needed
with FC1 kernels?
