Don't know if this works though. Following suggestion from Jeff Garzik limit max_sectors to the value I can actually test, i.e., 8MB. Therefore, version 2: Thanks Guennadi --- Guennadi Liakhovetski Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@xxxxxx> AM53C974A's Start Transfer Counter register has 24 bits, thus maximum transfer length is 16MiB. But the maximum I can test is 8MiB, so use that until somebody tests 16MiB. diff -u a/drivers/scsi/tmscsim.c b/drivers/scsi/tmscsim.c --- a/drivers/scsi/tmscsim.c 2006-10-02 00:21:56.000000000 +0200 +++ b/drivers/scsi/tmscsim.c 2006-10-02 00:21:46.000000000 +0200 @@ -2304,6 +2304,7 @@ .sg_tablesize = SG_ALL, .cmd_per_lun = 1, .use_clustering = ENABLE_CLUSTERING, + .max_sectors = 0x4000, /* 8MiB = 16 * 1024 * 512 */ }; /*********************************************************************** - 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
