Mike , Our driver gets called in with the following fashion through the queuecommand. scsi_request_fn() -> scsi_dispatch_cmd() -> rtn = host->hostt->queuecommand(cmd, scsi_done); We are using the "cmd" ( scsi_cmnd) as a pass through with out touching the "request_buffer" and "request_bufflen". We do not allocate memory similar to sg or st for page allocations. The request_buffer should already contain the scatter gather list built.

Did you also try the workarounds mentioned in the bugzilla, to allocate memory like sg and st? - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
