Hi, I found panic() in scsi_da.c. Please find the following. I think we should return with error without panic(). What do you think about this? scsi_da.c: 3018 } else if (bp != NULL) { 3019 if ((done_ccb->ccb_h.status & CAM_DEV_QFRZN) != 0) 3020 panic("REQ_CMP with QFRZN"); Best regards, Kohji Okuno
