So far I haven't noticed the corruption with 2.6.37.2, and I'm using ext3. I'm 
going to test with the debian kernel again soon here to see if the problem 
come back. I was just seeing if maybe it only happens when I've been using the 
system for a long time. I tend to have a lot of issues with this laptop once 
its been running for a long enough period (typically related to the intel_gfx 
drivers leaking and causing crashes or general unstableness). I had to restart 
my laptop a couple days ago, due to it not noticing the resume image.. but I 
didn't notice any corruption before that.
