I bought my mac pro about a week and a half ago. It shipped to me yesterday. Since then, I've done nothing but add my music from my old iTunes library and install some applications. I've gotten the gray screen of death (where the screen wipes down and says you need to restart aka Kernel Panic) 4 times already in probably 5 hours of usage. I haven't been running any applications when it's been happening, aside from safari and iTunes. It's random, I'm not doing any hardcore processing while it happens, just simple things like browsing the internet, listening to music. Any thoughts? Does anyone have any experience with this?
