@Theodore: Keep in mind the context of many of these reports, at least
here: an alpha OS (Jaunty) and not well tested, newly pulled in
versions of proprietary drivers. I wouldn't say linux users are used
to crashed all the time, but on an alpha with new proprietary drivers,
kernel panics aren't THAT rare until worked out. New upstream
application versions could also be doing silly things, they haven't
been thoroughly tested yet, that's the point of testing them :) Just
thought this reminder might help, it could be easy to not think about
if you are using EXT4 in a more stable environment. Having said that,
Alpha 5 has been awesome for me and I am now using it full time with
EXT4.

Bug description:
I recently installed Kubuntu Jaunty on a new drive, using Ext4 for all my data.

The first time i had this problem was a few days ago when after a power loss ktimetracker's config file was replaced by a 0 byte version . No idea if anything else was affected.. I just noticed ktimetracker right away.

Today, I was experimenting with some BIOS settings that made the system crash right after loading the desktop. After a clean reboot pretty much any file written to by any application (during the previous boot) was 0 bytes.
For example Plasma and some of the KDE core config files were reset. Also some of my MySQL databases were killed...

My EXT4 partitions all use the default settings with no performance tweaks. Barriers on, extents on, ordered data mode..

I used Ext3 for 2 years and I never had any problems after power losses or system crashes.

Jaunty has all the recent updates except for the kernel that i don't upgrade because of bug #315006
