Received from Mark Salyzyn, The aac_probe_container call blocks. This is an issue because it is called on occasion in the context of the queuecommand handler. Once in a blue moon this has resulted in a kernel panic sleeping during interrupt; or problems with some embedded system versions of the kernel that depend on queuecommand to not block. This ugly patch rewrites the aac_probe_container call into a new routine _aac_probe_container that is an asynchronous state machine to complete the series of operations. The legacy blocking aac_probe_container call used in other areas of the driver (during initialization scanning for all targets and in the separate hot-add/remove [aacraid] thread) merely issues _aac_probe_container and then simple spins calling schedule() waiting for completion.
