I've just got one: maybe the trouble is caused by the sio_putc procedure in sys/boot/i386/btx/btx/btx.S. It seems to be the only place in the boot code where 'ret <number>' instruction is explicitly used. A litmus question: do those experiencing the trouble all have BTX_SERIAL defined? P.S. BTW, is BTX_SERIAL documented anywhere? -- Andriy Gapon _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
