Testing at QLogic has found 4 more issues. These patches address these significant problems. - Extended Sense Data Errors UPDATE The previous fix used a scratchpad area that was already in use. Provide appropriate storage for this information - Code Cleanup Removed residual from overrun debug print Correct the information provided by these prints so as not to provide mis-leading information. Residual is not valid for over runs. - Fixed NULL pointer dereference in eh_device reset eh_device_reset may be called from scsi error handler or sg_reset, etc. When called from sg_reset, there will not be an associated srb. Also removed DEAD code (marker_needed variable in ha struct) - Removed unused hiwater code This frees up the number available IOCBs. Eliminates unnecessary eh_ escalations due to inability to obtain IOCB pkt for marker. Changes have been tested at QLogic.
