The prom_printf's I have been adding to track down troubles did not show. I could not determine if this was something to do with frame buffer or virtual terminal, but it interfered with prom_printf. I do have virtual terminals enabled for use with telnet / rlogin from un-beheaded boxes when it boots and have found no way to turn off the CONFIG_VT_CONSOLE if CONFIG_VT is set (editing .config doesn't). With the patch I get prom_printf's and printk's Without the patch I get prom_printf only And yes with -p I get nothing (I am sorry, once I got printk's on the screen I did not go back and test the -p so I don't know what it does after the patch). I would not mind testing patches that attempt to do this "right" Thanx Ray - To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
