I've just updated my system to r273822:
[root@taiga:~]# uname -a
FreeBSD taiga 10.1-PRERELEASE FreeBSD 10.1-PRERELEASE #0 r273822: Wed

The world and kernel are in sync. I'm still running the kernel built
after the same config as before. But, unfortunately, I've missed the
ability to run dtrace scripts. What have I missed ?
[root@taiga:~]# config -x /boot/kernel/kernel | egrep -i 'debug|kdtrace|ctf'
makeoptions WITH_CTF=1
makeoptions DEBUG=-g
options ALTQ_DEBUG
options USB_DEBUG
options IEEE80211_DEBUG
options DDB_CTF
options KDTRACE_HOOKS
options KDTRACE_FRAME
[root@taiga:~]# kldload dtraceall
kldload: can't load dtraceall: module already loaded or in kernel
[root@taiga:~]# dtrace -l | head
ID PROVIDER MODULE FUNCTION NAME
1 dtrace BEGIN
2 dtrace END

Thanks.
Eugene.
