dtrace + VBox kexts = kernel panic => Fixed in SVN

Reported by:	CrB	Owned by:
Component:	other	Version:	VirtualBox 4.2.4

Guest type:	other	Host type:	Mac OS X

Description

Loading dtrace (or anything depending on it) causes an immediate kernel panic if the VBox kexts are loaded. It does NOT require any running guests, or even the VBox interface loaded.

Post includes a backtrace of the crash. I can trivially reproduce the panic. I can do additional testing and/or supply additional info, if needed.

I've now tested on Mac OS X 10.7 and 10.8 and the panic does not occur. The kernel panic only occurs on 10.6 systems.

Thanks for the report! This will be fixed in the next maintenance release.

This is still happening on VirtualBox 4.2.6 r82870 on Mac OS X 10.6.8.

Right, the fix was done after 4.2.6 was released. Could you install this test build to confirm that the bug is fixed? Thank you!

Thanks. Confirmed fixed in 4.3.7 r83667.
