Kind of a silly request, but could you try rebuilding your kernel a second time? There were some changes to the ctf tools necessitated by the clang 3.4 import, and your kernel might contain CTF data emitted by the ctf tools before they were rebuilt. That can cause the problems you're seeing. Rebuilding a second time will cause the updated tools to be used. -Mark > > [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 > 3 dtrace ERROR > 4 fbt kernel camstatusentrycomp entry > 5 fbt kernel camstatusentrycomp return > 6 fbt kernel cam_compat_handle_0x17 entry > 7 fbt kernel cam_compat_handle_0x17 return > 8 fbt kernel cam_periph_done entry > 9 fbt kernel camperiphdone entry > [root@taiga:~]# dtrace -n 'syscall:::entry { @num[execname] = count(); }' > dtrace: invalid probe specifier syscall:::entry { @num[execname] = > count(); }: "/usr/lib/dtrace/psinfo.d", line 37: failed to copy type of > 'pr_uid': Type information is in parent and unavailable > [root@taiga:~]# > > Thanks. > Eugene. > _______________________________________________ > freebsd-dtrace@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-dtrace > To unsubscribe, send any mail to "freebsd-dtrace-unsubscribe@freebsd.org"
