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.

When the command is retried, if scsi_prep_fn decides to kill it then the scsi_cmnd will never be released.

But because ha->dpc_pid hasn't been set yet, qla2x00_free_device() tries to stop a kernel thread which hasn't started yet. It does wait_for_completion() against an uninitialised completion struct and the kernel hangs up. Fix it by initialising ha->dpc_pid a bit earlier.
