I just upgraded my kernel and userspace to head (r249552) and I notice that DTrace doesn't output anything until I hit ctrl-c. All previous "hits" on the probe appear lost. For example: # dtrace -n 'fbt::ether_output:entry' dtrace: description 'fbt::ether_output:entry' matched 1 probe (No output here. I waited a long time before the ctrl-c and I know the system is actively transmitting and receiving Ethernet traffic). ^C CPU ID FUNCTION:NAME 9 29354 ether_output:entry 8 29354 ether_output:entry 8 29354 ether_output:entry 8 29354 ether_output:entry Can anyone confirm or contradict this on a recent HEAD (around r249552 in my case)? Regards, Navdeep
