Subject: [2.6.32-rc4] + EXT4 corruption

Hello everyone, 

I somehow managed to corrupt some of my filesystem.

What I did was this:

in /etc/modprobe.d/alsa-base.conf (Kubuntu)

I added:

install snd-aloop /sbin/modprobe snd-aloop

Saved it, then ran, modprobe snd-aloop, the system started spawning many 
copies of modprobe, then machine started going though a swap storm, could not 
reboot safely, hit power button on laptop. When the system came back up, EXT4 
greeted me with severe errors on some opened files. It did repair filesystem 
however. It corrupted some configuration files that were open at the time of 
the shutdown.

I'm guessing no matter how much you attempt to replay a journal you still can 
get corruption such as this?

Thanks, 
Shawn.
