I can get firefox to crash on just about any kernel(FC6).  It's quite easy actually;  I just open a few tabs and especially while a closed one is loading(or sometimes the current one refreshing) I just scroll down the page real fast with the mouse wheel.  It took me a while to see some kind of pattern on it, but it seems that if it crashes, it crashes there.  It's also taken me a bit of time to remember to be careful, which is real silly to be modifying my behavior for a computer program(oh well).

Also, please don't remove the CFS scheduler, it's great!  I don't have any load balancing running with the AMD dual core and from watching the cpu loads in gkrellm, CFS totally outshines the the stock fedora's kernel.  Fernando, if you get a chance, please tell Ingo that I can't wait until CFS gets into the mainline kernel.  (I've been following the kernel scheduling stuff for some time now).
