I have seen a problem that matches your description, but not necessarily the same one: https://lists.freebsd.org/pipermail/freebsd-hackers/2016-July/049768.html > If you use default optimization level, a lot of fbt DTreace probes are > missing. You can try several different (orthogonal, even) approaches: - compile ZFS into the kernel - use higher optimization level, but add -fno-optimize-sibling-calls to CLFAGS - pkg install amd64-xtoolchain-gcc and then use CROSS_TOOLCHAIN=amd64-gcc command line argument for buildkernel -- Andriy Gapon _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
