I suffer from this problem on a HP/Compaq 8510w with ICH8. Instead of upgrading to a 2.6.29 kernel I'm currently running with 8.10 stable kernel (2.6.27-11) from the Intrepid repos. Which is fine for me. (Will not help you if you want to run ext4).
Still waiting for a kernel upgrade to solve the issue...
