KP when installing software that updates kexts
 

Hi guys,

Could anyone help me out with these panics I get whenever I try to update a driver or install software that updates or installs kexts.
For instance, I get this with Little Snitch and just now again with the new HP driver (2.5.2)
Both replace kexts so it must be related.

I then have to reboot into safe 32bit mode to run kextutility & repair permissions via terminal and even then it might not work and still post a kp.

Any idea's lads?

Thx much in advance
