Random crashes -

[takeawaydave]

Any hints on how to diagnose crashes on 10.8.1 - I have freshly installed over the weekend and slowly installed a few further apps since then but keeping getting annoying crashes (screen goes grey and box in the middle of screen says something like hold down grey button.. sure most have seen this screen before.)

 

the system.log is attached and time of penultimate crash was 16:24 and last one around 16:37.

 

The build is "almost" vanilla with a replacement of following 2 kexts:

 

IO80211Family.kext 3.2

IONetworkingFamily.kext 1.10

 

Thanks for any one able to help.
