Hi Folks, FWIW, here's my experience with the following current environment: Tyan K8W (s2875), bios 2.02 two 246 Opteron processors 4-Gb PC3700 RAM, with ECC SiL 3114 SATA, bios vers. 5.0.37 three Maxtor 6Y200M0 200-MB SATA disks, swap partition on each SuSE kernel 2.6.5-7.95-smp I wanted to try the SATA drives, this whole setup is a test to see if SuSE/Opteron is ready to replace our Sun Enterprise 4000 SPARC system, which is getting really long in the tooth. I experienced freeze-ups when running an FFT benchmark program when I first set the system up using the (then) latest "Beta" BIOS version. I then reflashed to the latest production BIOS, which took care of the benchmark freezing. Then, after further testing, I noticed that a recursive grep would cause the OOM (Out Of Memory) kernel module to kick in and say "KILLED", afterwhich the system silently crashes. After fiddling around with BIOS settings, I isolated the problem to the Northbridge Memory Configuration "Adjust Memory" choice being "auto" or "manual". If the choice is "Disabled" the OOM condition doesn't appear. I'm still having problems with the board reliably detecting the SATA disks, but this happens even before the OS is bootstrapped. I also can't get SuSE to recognize more than three SATA disks, but this may also be a MOBO problem. All in all, I'm very impressed with SuSE and its support for the Opterons. Good work, SuSE!

I have a Tyan dual Opteron and it freezes also. What I have found it usually freezes after I log out of kde do lately I have been locking my workstation instead of logging out and so far no freezes

I get a similar problem on different hardware:- MSI K8 Master2-FAR, opteron 242s, 2GB memory, nVidia FX5200 with NV driver
It locks up every 5-10 days. Current hypotheses being explored are:
- i/o problems (the manufacturers rather optimistically have put two large IDE drives on the same channel). I'm thinking of getting a separate IDE controller.
- software problems (it has happened quite a lot when using browsers)
- heating problems. One possibility is to install a fan near the memory modules. CPU temperatures seem OK.
- possible fluctuations in the mains power supply (I have a simple power filter, but maybe a more sophisticated UPS is needed).
