I added some memory to my linux box, for a total of 192 MB. I am trying to enable ECC in the BIOS and am having problems.
Linux runs fine with ECC enabled, except that I get the following during bootup:
Uhhuh. NMI received. Dazed and confused, but trying to continue You probably have a hardware problem with your RAM chips or a power saving mode enabled.
(I checked the BIOS settings, the power-saving stuff is turned off.)
My problem is that Windows 95 does *not* run fine when I enable ECC. It will eventually (after some time running apps on the machine) crash with a message that indicates a memory error (as I recall, it might have been parity error, NMI, whatever).
My question has to do with NMI handling in linux. I am using 2.0.33 with a few patches. Does this kernel disable NMI during normal operation? If this were a memory problem I would expect linux to log NMI interrupts in the syslog, would I not? I see no such messages.
I booted the memtest86 program and ran it for a day or two on the machine, with no errors detected.
