Hello, I've spend the past two days troubleshooting this issue with my Ubuntu 10.04 VirtualBox machine. I first upgraded the kernel to 2.6.35 and still had the problems. Long story short - what fixed this issue for me (running Ubuntu 10.04 (EXT4) as a guest on a Windows 7 x64 host) was the following post:

Virtual disk corruption on ext4 file systems

As soon as I changed my SATA drive to "use host I/O cache" all my problems were solved and performance increased dramatically. Hope this helps someone else someday.
