All the 16 bit values were gone yestereday... the current tenderbox failure is not SCTP.. at least not the ones I have seen... its : DHAVE_KERNEL_OPTION_HEADERS -include opt_global.h -fno-common -finline-limit=15000 --param inline-unit-growth=100 --param large-function-growth=1000 -fno-builtin -mcmodel=medlow -msoft-float -ffreestanding -Werror /src/sys/dev/ofw/ofw_console.c /src/sys/dev/ofw/ofw_console.c: In function `ofw_dev_open': /src/sys/dev/ofw/ofw_console.c:144: warning: implicit declaration of function `priv_check' /src/sys/dev/ofw/ofw_console.c:144: warning: nested extern declaration of `priv_check' /src/sys/dev/ofw/ofw_console.c:144: error: `PRIV_TTY_EXCLUSIVE' undeclared (first use in this function) /src/sys/dev/ofw/ofw_console.c:144: error: (Each undeclared identifier is reported only once /src/sys/dev/ofw/ofw_console.c:144: error: for each function it appears in.) *** Error code 1 and I don't think sctp is involved in this.. at least not to my knowledge R -- Randall Stewart NSSTG - Cisco Systems Inc. 803-345-0369 <or> 803-317-4952 (cell)
