Subject: ext4: oops on boot with root fs needing recovery

I had a crash and rebooted.  The root filesystem needed journal 
recovery, but ext4 crashed.

My root fs is ext3 (no extents), but I've been mounting it as ext4 to 
see how it turns out.

The oops is new; booting an older kernel successfully recovered the 
journal (I've reverted the rootfs back to ext3 for now).

I'm using the Fedora rawhide packages.  The crashing kernel is 
2.6.27-13.fc10.x86_64.  2.6.27-1.fc10.x86_64 worked OK.

Oops image is attached.  Unfortunately the top of the oops got cut off, 
though I thought I saw some mention of the "extents" option flying past.
