He discovered that reducing the maximum transfer size issued to the adapter to 128KB stabilized his system. This is related to an earlier change for the 2.6.13 tree resulting from Martin Drab's testing where the transfer size was reduced from 4G to 256KB; we needed to go still further in scaling back the request size. Here is the patch that tames this regression.

In some cases the reset handler can exit with the host_lock still held.

High Priority Queues have *never* been used in the entire history of the aac based adapters. Associated with this, aac_insert_entry can be removed, SavedIrql can be removed & padding variable can be removed. With the movement of SavedIrql out & replaced with an automatic variable qflags, the locking can be refined somewhat. The sparse warnings did not catch the need for byte swapping in the 'dprintk' debugging print macros, so fixed this up when this code was moved outside of the now refined locking.

The size of the command packet's scatter gather list maximum size was miscalculated in the low range leading to the driver initialization limiting the maximum i/o size that could go to the Adapter. There were no negative operational side effects resulting from this bad math, only a subtle limit in performance of the Adapter at the top end of the range.

In the rare instances where the adapter, or the motherboard, is misbehaving; driver initialization or shutdown becomes problematic. By introducing a 3 minute timeout on the first interrupt driven command during initialization, or the issuance of the adapter shutdown command during driver unload, we can resolve the lockup problems induced by common (but rare) hardware misbehaviors. The timeout during initialization, should it occur, is accompanied by a message presented to the console and the logs indicating that the user should inspect and resolve problems with interrupt routing.

Hotplug sniffs the AIFs (events) from the adapter and if a container change resulting in the device going offline (container zero), online (container zero completed) or changing capacity (morph) it will take actions by calling the appropriate API.

There are a few adapters that are capable of creating devices with this large of a capacity, but now that we have the large fib support in, the management applications will be capable of generating them. The problem is, once they are created, the driver will not be able to access the devices correctly without this patch.
