Hello, I was advised to move this thread [ http://marc.info/?t=124916632000003&r=1&w=2 ] to the linux-scsi mailing list. In my opinion the original problem descriptions can be considered as a follow-up to a year old thread on "JMicron JM20337 USB-SATA data corruption bugfix" [ http://marc.info/?l=linux-kernel&m=121653150327283&w=2 ]. The JMicron bridge is connected to a SATA disk with genuine errors (bad sectors, just in case: I am not going to use it but to recover some data from it). Unfortunately when a bad block is read no error is returned, instead a caller is blocked indefinitely (at least for two hours or until the USB cable is removed). The system log is filled with repetitive sd 3:0:0:0: [sdf] Sense Key : 0x0 [current] sd 3:0:0:0: [sdf] ASC=0x0 ASCQ=0x0 Alan Stern has suggested that this should be fixed as following: AS> Tell them that scsi_end_request() mustn't call scsi_requeue_command() AS> if bytes == 0. Is this the right thing to do? Thanks -L P.S. Please let me know if the CC: list is too long. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
