 On a second look I seem to have found the culprit in an obscure block
 of e2_setup_block_mode().  This patch should mend the problem without
 noticeable side effects.

   	DBG(1, "max req size: %d\n", sanei_scsi_max_request_size);
   
 + #if 0
   	if (s->lcount < 3 && e2_model(s, "GT-X800")) {
   		s->lcount = 21;
   		DBG(17,
   		    "%s: set lcount = %i bigger than sanei_scsi_max_request_size\n",
   		    __func__, s->lcount);
   	}
 + #endif
   
   	if (s->lcount >= 255) {
   		s->lcount = 255;
 
 
 It's a mystery why the driver should ignore
 sanei_scsi_max_request_size at all.  This looks more like a bug rather
 than a porting issue.
