Description Magnus Anderson 2005-07-21 14:43:26 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050513 Fedora/1.0.4-1.3.1 Firefox/1.0.4

Description of problem:
After clean installation of Fedora Core 4 the installed initrd does not work.

The error that gets outputted after "Uncompressing kernel..." are
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown block(0,0)

When booting there was no sum and size numbers after the initrd string right after the kernel as it should do.

This error was solved by doing:
1. Starting the computer in rescue mode with the DVD
2. Removing the precompiled initrd in /boot
3. Running mkinitrd /boot/initrd-2.6.11-1.1369.img 2.6.11-1.1369_FC4

The filesystem looks like this
/dev/hda1 reiserfs /boot
/dev/hda2 LVM
/dev/VolGroup00/LogVol00 swap
/dev/VolGroup00/LogVol01 reiserfs /
/dev/VolGroup00/LogVol02 reiserfs /home

If this problem occured because I used reiserfs on the /boot parition or becuase I use LVM I still don't know.

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

How reproducible:

Steps to Reproduce:
1. Install Fedora Core 4 with a LVM partition and all reiserfs
2. Reboot and get a kernel panic error

Actual Results:  Kernel panic - not syncing: VFS: Unable to mount root fs on unknown block(0,0)

Expected Results:  Actually booting the computer

Exact error after the installation that I get is...

root (hd0,0)
Filesystem type is reiserfs, partition type 0x83
kernel /vmlinuz-2.6.11-1.1369_FC4 ro root=/dev/VolGroup00/LogVol01 rhgb quiet
[Linux-bzImage, setup=0x1e00, size=0x18e473]
initrd /initrd-2.6.11-1.1369_FC4.img

Uncompressing Linux... Ok, booting the kernel.
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

This report targets the FC3 or FC4 products, which have now been EOL'd.

Could you please check that it still applies to a current Fedora release, and
either update the target product or close it ?

Fedora Core 4 is no longer maintained.

Setting status to "INSUFFICIENT_DATA". If you can reproduce this bug in the
current Fedora release, please reopen this bug and assign it to the
corresponding Fedora version.
