Hi guys, I just today got a couple of errors like this on a Dell D610: BillMurray kernel: Uhhuh. NMI received for unknown reason b0 on CPU 0. BillMurray kernel: You probably have a hardware problem with your RAM chips BillMurray kernel: Dazed and confused, but trying to continue I tried running RAM self-tests, but they report all is fine. Should I worry? About 2 weeks ago I closed the laptop with no user logged in, forgetting suspend-to-ram would not work. An hour later I took it out of my bag, very hot. Very. It was all funny - but after a reboot seemed OK, but I suspect it has been taking longer to boot/login. Hard to be sure, and this was 2 weeks ago, the error started today. Any thoughts anyone? Thanks, Bill
