Bug 129667

Does it work if you remove rhgb and quiet from your boot options?

It boot fine if I remove "rhgb quiet"

I was having this same kernel panic problem with kernel 509.  Removing
"rhgb quiet" from the boot options also allowed me to boot.

Could you try again with mkinitrd 4.0.4 (will be at
http://people.redhat.com/~katzj/mkinitrd/ as soon as it's done building)?

I've tried mkinitrd 4.0.4-1 (with kernel 478) - I still get a panic
(however a different error)

----
Red Hat nash version 4.0.4 starting
mount: error 6 mounting ext3
switchroot: mount failed: 22
Kernel panic: Attempted to kill init!

----

removing 'rhgb quiet' is a bit more verbose - but stops with the same
error

Can you provide the more verbose bit? 

Still observing failure with latest mkinitrd-4.0.4-1.  I am able to
bypass the failure by simply removing "quiet" from the kernel boot args.

Ok - I'm typing in things I see on the screen (so ignore typos).. I've
also updated today's rawhide - which has kernel 517 (and the following
messages are with 517)

The same panic for kernel 515 and 517:

Mounting root filesystem
mount: error 6 mounting ext3
Switching to new root
switchroot: mount failed: 22
Kernel panic: Attempted to kill init!

But 509 is fine.  I have up2date rawhide with 
mkinitrd-4.0.4-1.

mkinitrd 4.0.5 from http://people.redhat.com/~katzj/mkinitrd/ should
be better.  Sorry, was asleep at the wheel or something yesterday.

removing "rhgb quit" works now - but with the flags enabled - I'm back
to the original problem:

exec of init failed!!!: 14

Can you do

wget http://people.redhat.com/~katzj/nash-test ; cp nash-test
/sbin/nash; /sbin/mkinitrd -v -f /boot/initrd-ver-test ver

(Substituting ver and the name of the initrd appropriately of course)
and see what it tells you?  Also, could you attach your complete
grub.conf?

And then boot that initrd?  (it should then say what tries to get
exec'd as init that fails)

w/ custom /sbin/nash

exec of init (/sbin/init) failed!!!: 14

I get the same message as well:
---
exec of init (/sbin/init) failed!!!: 14
---

And booting without "rhgb quiet" continues to work.

Okay added even more debugging printfs to nash's exec of init.  New
nash at http://people.redhat.com/~katzj/nash-test-2.  If you could
grab that and remake your initrd and let me know what output you get,
that would be helpful.

Here is my boot parameters from grub.conf:
kernel /vmlinuz-2.6.7-1.517 ro root=LABEL=/ vga=0x317 rhgb selinux=0 quiet

I got your new nash.  Booted and this is the error:
---BEGIN---
initargs[1] ro
initargs[2] root=LABEL=/
initargs[3] vga=0x317
initargs[4] rhgb
initargs[5] selinux=0
initargs[6] quiet
exec of init (/sbin/init) failed!!!: 14
--END--

Now what I found is that it did not matter if I took out rhgb, quiet,
vga=0x317.  What mattered is if I had < 6 initargs.

args <6 will boot.  args >= 6 no boot.

Hope this helps.

Ok I see the same behavior (args<6 => boot will work) as well. I
currently have:
kernel /vmlinuz-2.6.7-1.517 ro root=LABEL=/ selinux=0 rhgb quiet acpi=off

Removing 'acpi=off' worked.

Screendump with failure is:
----------
Red Hat nash version 4.0.5.1 starting
initargs[1]: r0
initargs[2]: root=LABEL=/
initargs[3]: selinux=0

mkinitrd-4.0.6 building with a variety of fixes (will be in the same
place on my people page once its done)

mkinitrd-4.0.6 appears to fix the probem for me. kernel now boots fine
with 6 options.

mkinitrd-4.0.6 resolves this issue.  Please re-open if the problem
resurfaces in the future.
