I switched my laptop over to ext4 yesterday. Then I used tune2fs to
enable the features from mke2fs.conf's defaults for ext4 (some failed).
It worked fine initially but today I am getting a panic when the machine
boots: http://csclub.uwaterloo.ca/~mspang/panic.jpg .
Let me know if there's anything I can do to rescue it. Otherwise I'll
just reinstall.
Thanks.

Which version of the kernel ? Did you try ext4 patchqueu at
http://repo.or.cz/w/ext4-patch-queue.git . I have a patch queued
for fixing a crash I found. I am not sure whether it is same one

What version of the kernel are you using, and what patches (if any)
have you installed? Are you using a distribution kernel?

Looks similar to https://bugzilla.redhat.com/show_bug.cgi?id=467161,
which I was just alerted to, and I'm looking into it.

Michael,
Do you have a rescue CD with e2fsprogs 1.41.0 or later? If it's the
problem Aneesh thinks it is (and I agree), running e2fsck in preen
mode should fix the problem.

Eric, I suspect this patch in the ext4 patch queue should fix things.

Linus' head as of 2 days ago, at
278429cff8809958d25415ba0ed32b59866ab1a8. I looked at your
tree yesterday and saw that nothing had been applied since.
Merging the patch queue a moment ago made no interesting changes.
Thanks,

Ah, you're right. I thought I had that in the fedora kernel, so was
looking for something new, but ... nope. grr.
/me runs off to update.
Thanks,

Er, yes it did. I'll try e2fsck and booting with the patch queue merged.

BTW, since I've been doing a lot of work on the patch queue, including
recently rebasing off of 2.6.27-git5 so I could pick up the blkdev
discard patches, I've been maintaining the ext4-stable branch in the
ext4 git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.
http://git.kernel.org/?p=linux/kernel/git/tytso/ext4.git
It contains all of the patches that have gone upstream to Linus,
against the baseline 2.6.27 kernel. We still need to cherry-pick the
most critical bugs fixes in that branch to submit to the -stable
kernel series....
