DTrace & Debian/Jessie Monday, 01 December 2014  
Someone reported a bug in dtrace whereby execve() wasnt tracing. I created a VM and started testing, and can confirm this. Looks like dtrace is getting confused by the new rewritten syscall assembler. I have a working version for this in my testbed, but I found that changes to the IPI code in the kernel are making any dtrace probes extremely unreliable - looks like a 1:N chance of seeing output (where N is the number of cpus you have).

I have some similar issues in Ubuntu 14.04 - hopefully similar issues.

Hope to have a new release shortly in a few days.
