A quick data point: I tested a build with gcc 4.6.1, uClibc 0.9.32, NPTL, and both iperf and dbus-daemon start fine for me: # iperf Usage: iperf [-s|-c host] [options] Try `iperf --help' for more information. # dbus-daemon No configuration file specified. dbus-daemon [--version] [--session] [--system] [--config-file=FILE] [--print-address[=DESCRIPTOR]] [--print-pid[=DESCRIPTOR]] [--fork] [--nofork] [--introspect] [--address=ADDRESS] [--systemd-activation] # uname -a Linux buildroot 2.6.38.8 #1 Fri Sep 30 20:24:38 UTC 2011 armv5tejl GNU/Linux My target optimization options is: BR2_GCC_TARGET_TUNE="arm926ej-s" BR2_GCC_TARGET_ARCH="armv5te" BR2_GCC_TARGET_ABI="aapcs-linux" Therefore, I guess that the problem might be iwmmxt related. Can you try with "lower" optimization options ?
