Random Kernel Panics since 10.7.4 update.

[daz1uk]

Ok on 10.7.3 my system was running pretty much spot on, since the update to 10.7.4 im getting random kernel panics, by random I mean that sometimes it will boot and sometimes it won't.

 

 

 

I have attached a couple of images and would be grateful if anyone has anybidea on how I can solve this.

 

Thanks.
