During buildworld I get: Jul 11 18:28:41 server /kernel: NMI ISA 2c, EISA ff Roughly about 10-40 times during the build. If I boot a uniprocessor kernel this problem doesn't occur. Also, when I first put the machine together I ran with a single CPU installed and also noticed this problem (probably to a lesser extent), with a SMP kernel seeing 2 CPUs because of the HT. I have tried disabling ACPI in the BIOS. I ran memtester for about 7 runs without any errors. >From the list archives I read that these errors are indicative of a hardware problem but I am unsure of this seeing that a uniprocessor kernel does not exhibit the problem. The machine has never panic'd or hung, but obviously these errors aren't very encouraging. (Disk controller is 3ware 7006-2 if that makes any difference) Anyone have any clues to what's going on here? -Paul-
