I posted in the past about problems with the 2200S. I think I've managed to solve my problems. Here's my fix: Flashed the firmware back to 7244 firmware. Booted from a disk that used 2.4 kernel. Installed the driver (followed Adaptec directions) for the 7348/7349 firmware that was released Dec 17th even though Adaptec states it's for the 7348/7349 firmware. My system now boots without problem using hardware raid volumes. I've eliminated the system hangs and very long timeouts that I was experiencing. Adaptec may not support this, but so what, they weren't providing me with even marginally good support as it was. Now the only message I get from the system is that aacraid taints the kernel and that is due to the non-GPL Adaptec driver. I can live with that. At least the system stays up now, and its very responsive. John
