 With this patch applied to -6 I still see pretty much repeatable locks up
 (endless loop) here:
 
 (gdb) list *(iscsiioctl+0xb76)
 0x1ca0 is in iscsiioctl (/usr/src-6/sys/dev/iscsi/iscsi_ioctl.c:782).
 777             session->active_connections++;
 778     
 779             TAILQ_INIT(&old_waiting);
 780             while ((ccb = TAILQ_FIRST(&connection->ccbs_waiting)) != NULL) 
{
 781                     TAILQ_REMOVE(&connection->ccbs_waiting, ccb, chain);
 782                     TAILQ_INSERT_TAIL(&old_waiting, ccb, chain);
 783             }
 784     
 785             init_sernum(&connection->StatSN_buf);
 786             wakeup(connection);
 
 However, my randomly failing device discovery seems to be fixed.
