Had another crash and got the popup screen at boot, here is the output from that. Also got the same symptoms in SafeMode as well, a crash after a day and a half; logged if but not working on it at the time. Some other information, not sure if this is related as i hear of a number having the same issue but I keep having applications crash, mostly the browsers (Chrome an Safari) but also Mail and my Desktop Clock app. not so much other apps. I use OpenOffice a lot and it's been stable (until the system crashes). I run fsck periodically after crashes to keep my FS in good shape and I TimeMachine my main drive. .
