SuSE 9.2 on dual AMD with 4GB crashes
![](https://seccdn.libravatar.org/avatar/195baf62d04dd15d29a9568ccb72bbbe.jpg?s=120&d=mm&r=g)
Hi, I just upgraded my machine from 2 to 4 GB main memory and now get bad crashes as soon as memory starts to fill up above the 2GB limit. A rather short run with memtest86 (1 hour) reveils no problems. System details: SuSE 9.2 Professional Stock kernel from kernel-smp-2.6.8-24.17 Tyan S2466 motherboard Original BIOS (can I get the version from Linux?) 2 AMD 1600+ CPUs (AthlonMP) 4*Kinston 1GB modules (KVR266X72RC25L/1G) Matrox 450 video card Soundblaster live audio Kernel says system has 3.7GB main memory, which is about as expected. It produces crashes in applications (gcc internal errors on code that compiles fine with only 2GB main memory) as well as kernel oopses and total freeze. My most important question is whether this is almost certainly a hardware problem or whether there are known problems with this kernel on this type of hardware and 4GB (system is rock-solid on 2GB). Any ideas? --- Jan

Try running with just the new memory installed to see it you still have problems. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998 "The day Microsoft makes something that doesn't suck is probably the day they start making vacuum cleaners." -Ernst Jan Plugge

I already got that advice and I'll try it if I get near the machine next week. Before doing lots of experiments, not making friends as the machine is heavily used continuously, I'd like to see some confirmation that current 2.6 kernels are generally robust on dual AthlonMP with 4GB. I've seen some messages in various forums (kernel and Beowulf lists) claiming problems with Tyan boards and 4GB, but these messages were all very old, so I have no clue whether they are still relevant and there were no clear answers. Cheers --- Jan

You'd be better off asking on the suse-amd64 mailing list. Philipp
