Created attachment 531674 [details] Kernel messages captured via serial console Description of problem: System displays a panic (unable to load init) when using initramfs which matches kernel version. Worked OK with kernel 2.6.38.8-35, which I'm still having to boot from, but not with any version of 2.6.40. Version-Release number of selected component (if applicable):2.6.40.4-5, 2.6.40.6-0 How reproducible: Steps to Reproduce: 1. Power on system, select 2.6.40 kernel from Grub menu 2. 3. Actual results: Kernel panic: [ 10.525076] Failed to execute /init [ 10.567098] Kernel panic - not syncing: No init found. Try passing init= opt ion to kernel. See Linux Documentation/init.txt for guidance.

does /boot/initramfs-2.6.40.6-0.fc15.x86_64.img exist ? Is it roughly the same size as the other initramfs files ? Try recreating it with dracut /boot/initramfs-2.6.40.6-0.fc15.x86_64.img 2.6.40.6-0.fc15.x86_64
Thanks for the reply. The 2.6.40 initramfs is smaller than the 2.6.38 one: # ls /boot/initramfs* -rw-r--r--. 1 root root 14445734 Jul 16 08:48 /boot/initramfs-2.6.38.8-35.fc15.x86_64.img -rw-r--r--. 1 root root 11629993 Oct 9 22:38 /boot/initramfs-2.6.40.6-0.fc15.x86_64.img # dracut --force /boot/initramfs-2.6.40.6-0.fc15.x86_64.img W: Possible missing firmware "ql2400_fw.bin" for kernel module "qla2xxx.ko" W: Possible missing firmware "ql2322_fw.bin" for kernel module "qla2xxx.ko" W: Possible missing firmware "ql2300_fw.bin" for kernel module "qla2xxx.ko" W: Possible missing firmware "ql2200_fw.bin" for kernel module "qla2xxx.ko" W: Possible missing firmware "ql2100_fw.bin" for kernel module "qla2xxx.ko" W: Possible missing firmware "cbfw_fc.bin" for kernel module "bfa.ko" W: Possible missing firmware "ctfw_cna.bin" for kernel module "bfa.ko" W: Possible missing firmware "ctfw_fc.bin" for kernel module "bfa.ko" W: Possible missing firmware "aic94xx-seq.fw" for kernel module "aic94xx.ko" # ls /boot/initramfs* -rw-r--r--. 1 root root 14445734 Jul 16 08:48 /boot/initramfs-2.6.38.8-35.fc15.x86_64.img -rw-r--r--. 1 root root 10990984 Nov 8 20:19 /boot/initramfs-2.6.40.6-0.fc15.x86_64.img - and no improvement unfortunately. It's possible I may have tried running dracut before while troubleshooting, so the previous 2.6.40 initramfs may not be the distributed one. I can make the initramfs file available somewhere if that is useful?
Do you have all the fedora updates installed, including dracut and lvm2? Also, the current kernel is now 2.6.41, have you tried that?
I have tried the most recent kernel (2.6.41.5-1) and the issue remains (I have now grabbed another set of kernel messages for that, but they are not really different). dracut & lvm: # rpm -q dracut dracut-009-12.fc15.noarch # lvm version LVM version: 2.02.84(2) (2011-02-09) Library version: 1.02.63 (2011-02-09) Driver version: 4.19.1 # rpm -q lvm2 lvm2-2.02.84-4.fc15.x86_64 I believe that all my updates are in order - I did a yum update today and plenty of new stuff appeared.
I have this problem with dracut-016. 014 works in booting, but in rebooting it tries to unmount /usr and predictably it fails; then it says /shutdown: line 97: reboot: command not found; then kernel panic, attempted to kill init. cmdline is rw root=LABEL=wd1root rootfstype=xfs i915.modeset=1 vga=6 noisapnp enforcing=0 selinux=0 printk.time=1 log_buf_len=512k nodmraid nompath raid=noautodetect random_debug=0 processor.max_cstate=0 usbhid.mousepoll=1 memtest=0 rd.dm=0 rd.md=0 rd.lvm=0 rd.luks=0 rd.info plymouth.enable=0 vconsole.keymap=fi-latin9 vconsole.font=lat9w-08 SYSFONTACM=iso15 LANG=en_US.UTF-8

(In reply to comment #7) I don't have this problem anymore.
> > you can try: https://admin.fedoraproject.org/updates/dracut-009-15.fc15 I have now upgraded to F16 and the problem went away with the upgrade, so I'm afraid I can't comment on whether that fixes it, sorry!
