[dtrace-discuss] System hangs when invoking DTrace script

[Matty]

Howdy,

I installed Nevada build 49 in a parallels VM on my intel mac mini,
and when I run the following DTrace script:

$ cat follow.d
#pragma option D flowindent;

pid$target:::entry,
pid$target:::return
{}

$ cat format.cmds
disk
0
exit

$ dtrace -s follow.d -o follow.out -c "/usr/sbin/format -f format.cmds"
dtrace: script 'follow.d' matched 13641 probes

The system hangs, and the following error is written to the console
and /var/adm/messages:

Dec  6 20:10:34 sparky unix: [ID 988528 kern.warning] WARNING:
Unexpected INT 1 in user mode, dr6=ffff0ff0

Is anyone able to reproduce this? Any thoughts what might be causing it?

Thanks,
- Ryan
