I am running main-n266450-a592812327de with a GENERIC-NODEBUG kernel. # kldload tcp_rack kldload: an error occurred while loading module tcp_rack. Please check dmesg(8) for more details. In dmesg: KLD tcp_rack.ko: depends on tcphpts - not available or version mismatch linker_load_file: /boot/kernel/tcp_rack.ko - unsupported file type So you have to build a kernel with "options TCPHPTS" first? -- Herbert
