Hi Michael,
using ZFS by any chance? If yes - please truss a process (e.g. DBWR) and check for the following exemplary errors:

---

14051/1:     kaio(AIOWAIT, 0xFFFFFFFFFFFFFFFF)      Err#22 EINVAL  
14051/1:     kaio(AIOWAIT, 0xFFFFFFFFFFFFFFFF)      Err#22 EINVAL  
14051/1:     kaio(AIOWAIT, 0xFFFFFFFFFFFFFFFF)      Err#22 EINVAL  

---

.. if so you are hitting a known Solaris / ZFS bug (but can not find the corresponding ID right now).
