Chris,
 I found this white paper from metalink to be helpful.

Asynchronous I/O (aio) on RedHat Advanced Server=20 Version 2.1 - 3.0 (Note:225751.1)

Everything I have read advocates aio on RHAS 3.0.

I have heard also it can cause crashes and corruption, but found no meat = to that statement no open bugs for 9205/9206 on rhas 3.0 Anyone with any = hard facts as to real issues or successes? Anyone done an IO slave implementation in Linux/RAC? IO slaves in many ways are more robust and multi purpose than asych IO = functionality...but I'm wondering how that performs with RAC.

Yes, I would and will test either or both before consideration with = prod, but looking for others insights if they have been down the road.
