[Bug 396286] Re: [Geode LX] [OLPC] 2.6.31-generic: kernel panic near the end of initramfs

[Martin-Éric Racine]

It seems that we have some progress.

In an attempt to debug this issue, I compared notes with someone on
Fedora for whom the same hardware works.  As a test, I used their kernel
2.6.31 config (with a couple of small modifications to build specific
drivers as built-in) as attached to build my own kernel using make-kpkg.
Much to my amazement, this kernel boots fine, as long as I specify
root=/dev/sda1 on the GRUB cmdline.

However, for some reason, kernel-package no longer creates an
initrd.img, even when the --initrd option was specified to build the
kernel-image target.  Yet, as soon as I created one using "sudo update-
initramfs -k 2.6.31.12-geodelx -c" and rebooted, the kernel failed to
boot as before.

Just to be safe, I deleted the initrd and rebooted again, letting udev
perform its work after /sbin/init has been launched by the kernel. Lo
and behold, it worked again!

As such, it seems that something that gets included in the initramfs
image is what messes with the ACL code and destroys some inodes and
makes the kernel crash in a non-recoverable way.

Interestingly enough, we still get the previous error messages when
booting with this barebone kernel, without an initrd.img, but the error
is non-fatal.  The output of dmesg -r is attached next.
