The board is an Asus A8N-E Premium (NForce4 chipset). I tried both new newest BIOS 1009 and the newest beta BIOS 1011-001, no change. CPU is a dual-core Opteron 170. FreeBSD is a few days old 7-current, SMP kernel, AMD64. I also noticed that device probing becomes much slower with 4 GB and remapping as opposed to running 2 GB or 4 GB with no remapping. The probe of the nve GbE in particular takes long, about 20 seconds. Linux on the same board with 4GB+remapping panics with PCI-DMA: high address but no IOMMU In Linux you can work around it with boot option iommu=soft Is this just the usual "Asus has BIOS siesta again" situation or can I do anything about it? I like the board otherwise, without remapping it works best of what I tested for my new server so far. dmesg, pciconf etc are on http://www.cons.org/cracauer/machines/wings-a8ne-premium/ Martin -- %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Martin Cracauer http://www.cons.org/cracauer/ FreeBSD - where you want to go, today. http://www.freebsd.org/
