When the box locked up I couldn't even drop into the kernel debugger from the serial console. neither the BREAK signal nor the alt key sequence invoked it. > > - Have you tried using other network cards ? > ( yeah that sucks I know ) Nope. Machine is brand spanking new. Was in service a whole of 5 days before it locked up. The twin of this machine also has issues with the BIOS reporting "memory size changed" while the machine is running... so I'm a bit concerned that there is some generic problem with the K8SR and a megaraid controller. But that one never had any complaints about the ethernet, and the memory size error persisted across two motherboards. I have yet to try the other ethernet port on this box as well. > > - Are you absolutely sure that all the disks are working ? > ( there have been reports of amr cards acting strange with > silently failing disks ) The megaraid bios showed all disks as active. How would one tell if you had a silently failing disk? :-( > - Have you got the ufs fixes recently backported to releng_5 ? If it was prior to March 22, then yes I have them.

Yes, it is good.... until you can't figure out if it is your hardware or software flaking out on ya... Thanks so much for responding. For price-no-object, which vendor would you choose for an AMD system today? Same question if price is somewhat of a concern. Thanks.
