KP when installing driver/software that replaces kexts

[Snow]

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

I have the same exact problem... after installing anything (update itunes, xcode) i can only reboot in safe mode.. and even after repairing permissions with kextutility, it wont work...
