Can you reproduce this reliably?  What sort of things did fsck report?
Was it after a suspend/resume that failed?

I'm using a Ubuntu 9.04 with a 2.6.32-rc1+ mainline kernel, and it
works fine for me.  So we really need many more details what sort of
filesystem corruption (not just "bad things"), and more details about
what you did while testing a newer kernel, and what sort of things
fsck complained about.
