Absolutely.  Might be worth rebooting with the rescue disk and running
memcheck for a while to see if the main memory is the issue.

I had a stick of memory go bad on me once, and all of a sudden the machine
would boot in rescue mode and do an fsck fine, but when booted normally it
would go screwy halfway through bootup and corrupt the filesystem.  My theory
after I figured it out and removed the bad memory was that given a particular
kernel, it just so happened that the filesystem code was always getting loaded
into the same corrupt memory...
