We have several SMP machines around here, one is a ASUS CUV4X-D based system. This machine never have had any lockups as you described. Another system, a TYAN Thunder 2500/Slot 1 system with ServerWorks ServerSet III/HE chipset had today its 'spontanous' reboot. With TYAN's mainboard I had a lot of trouble and it seems not to be only a issue of the chipset itself! TYAN Thunder and ASUS CUV4X-D have problems with IRQs, I guess, especially when using more than one Intel EtherExpress (fxp) NIC. Our TYAN Thunder SMP machine ran the last 7 months without any sign of reboot under heavy load, and I cvsupdate weekly or nearly every second day (RELENG_4). And yesterday I did the last cvsupdate and today I fall back into the weird spontanous reboots. It seems really weird to me ... By the way: we do not use any ATA device on all machines, both SMP systems use AMI MegaRAID or Enterprise RAID controler (PCI 64/66 in TYAN and in a 32 Bit slot in the ASUS ...). Oliver -- MfG O.
