Ubuntu Jaunty ext3 --> ext4 upgrade issue

[Tim Gardner <tim.gardner@canonical.com>]

Ted,

I've encountered a situation where the patches that you've proposed for
stable updates might be causing some issues. This user ivoks appears to
have an upgrade issue. I assume he's enabled ext4 on an existing ext3
file system. Hopefully I can get more details. Have you seen anything
like this?

After looking at your for-stable branch, I think I'm missing a couple of
jbd2 patches. Could they be significant?

rtg

<ivoks> i'm getting 'Invalid or unsupported executable format' from grub
on all jaunty's generic kernels since (including) 2.6.28-7
<rtg> ivoks: you must have HW issues. Surely lots of folks would have
been howling by now.
<ivoks> could be... but -6 works :/
<ivoks> even after reinstall of all kernels
<rtg> have you fsck'd ?
<ivoks> could try that...
 it's ext4
<rtg> ivoks: is it an ext4 upgrade, or was it install time formatted ?
<ivoks> upgrade
<rtg> hmm, there were a bunch of ext4 changes that went into -7.18
<ivoks> right, i've noticed that
<rtg> ivoks: any change you could build a kernel with all of those
patches reverted? I expected them via stable updates by now, but perhaps
Ted has been finding issues with them.
<ivoks> i could try...
<rtg> ivoks: they are all labeled 'SAUCE: (revert before 2.6.28.y
update) ext4:'
<ivoks> thanks
<ivoks> only 21 commits :)
<ivoks> is it possible to build i386 kernel on amd64?
<rtg> ivoks: you have to chroot the build.
<ivoks> oh, right!
<ivoks> rtg: so, reverting all ext4 commits since -6 did the trick
<rtg> ivoks: can you file a bug with the specifics, and your results
that I can pass on to Ted ?
<ivoks> yes, but later... i have to rush now :/
 take care
