kernel crashes on boot
Last modified: 2007-11-30 17:11:17 EST
Description of problem:
Can't mount root filesystem from initrd. Last working kernel I tried is
Fully up-to-date rawhide.
Version-Release number of selected component (if applicable):
kernel-2.6.14-1.1696_FC5 (also 1.1680_FC5)
Steps to Reproduce:
Creating root device.
Mounting root filesystem.
mount: error: No such device or address mounting /dev/root on /sysroot as ext3
Setting up other filessytems
Setting up root fs
setuproot: moving /dev failed: No such file or directory
no fstab.sys, mounting internal defaults
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
Switching to new root and running init
unmounting old /dev
unmounting old /proc
unmounting old /sys
switchroot: mount failed: No such file or directory
Kernel panic - not syncing: Attempted to kill init!
initrd is suspiciously small, only 937244 bytes, 1.1660 has 1397242.
Reinstalled the kernel to make sure it wasn't some glitch when installing it, no
Everything (except /boot) is on LVM, SATA disk
damn, you get all the oddball bugs :-)
that initrd size difference does sound odd. Does your /etc/modprobe.conf look sane ?

Requested /etc/modprobe.conf file
The /etc/modprobe.conf file looks sane to me, and has worked forever on this
BTW, today's 2.6.14-1.1707_FC5 crashes just the same.

Difference in contents of initrds
I just unpacked the initrd's for the working and last broken kernel. The reason
for the crash is crystal clear now: lvm is missing. See the attached "diff -u"
between the "ls -R"'s for both (oird is old, nird is new).
I just remade an initrd for the working kernel with mkinitrd-5.0.11-1, and it
shows no difference in contents to the original. And creating an initrd for the
new kernel shows no difference in contents to the working one...
Now booting 2.6.14-1.1707_FC5 with hand-built initrd... Yep, works.
Thanks for the help!
