I had especially on the TYAN Thunder 2500 problems with APM enabled, but why use this seneseless feature in an server environment? Our ASUS CUV4X-D had also APM problems, I deselected it - and things were fine as before. Another issue is networking, NICs and IRQ with FreeBSD. I made the same experiences like you with more than one NIC enabled and used in an SMP system. While UP systems does obviously not have any problems with more than one NIC (we have a bridging firewall with two NICs, fxp type EtherExpress 10/100 Pro+, never saw any problem if the NICs are placed in the right PCI slots on the ASUS A7V mobo), SMP machines does. Especially those with newer chipsets. Our older SMP system, based on two Intel PII/350 on a GigaByte and Bx440 chipset worked without problems with two Intel NICs, but the TYAN Thunder 2500 did not. Our ASUS does not have a built in NIC and it worked with FBSD 4.3 without problems and in SMP mode using two NICs (activated and therefore up and under heavy load!). As I reported, the problems went away on the TYAN when replacing the RAID controller and not activating the built in NIC. I guess this has to do with IRQ sharing and the IRQ routing because I ran into much trouble when I updated the firmware of the AMI Enterprise RAID controller (nothing else!) and after a reboot, this controller obtained another IRQ and after a couple of seconds the system locked up - until I placed the controller in a PCI 64/66 slot. On Linux I never saw similar problems, but Linux has several other issues, and especially performance impacts, which can be measured if both systems are up and running stable. -- MfG O.
