No idea what's going on there - what can I do to find out more about why this happens? I'd be glad to provide any more info if needed!
Maybe it's something to do with fglrx? It's output is the last before the NULL pointer dereference...or anything else specific to look for in kern.log?
My system:
Asus Z77 Pro3
Intel Core i-7 3770K
XFX Radeon HD 7870 Dual Fan
60GB SSD (OCZ Vertex2)
1TB HD (Samsung)
Thanks for any help!
See (hopefully the relevant) part of the kern.log file:
