Hi. I just installed FreeBSD 5.4 on a Tyan K8QS. It has two dual-core opteron 870's, 8 GB RAM, amr-raid using two drives in raid-1 and two bge onboard-nic's. I had problems recompiling kernel and world until I added hw.physmem=3D4GB to /boot/loader.conf. So I tried FreeBSD 6.0 to see if the problem went away. Same thing, so I added hw.physmem=3D3GB (again) and recompiled the kernel, this time omitting all ata-related code. After removing hw.physmem from loader.conf and rebooting the ata-free kernel world and kernel compiles without problems. Omitting ata isn't a big deal since the only ata-device is the dvd-drive. Since 6.0 just came out the door it may be premature to ask whether I should go for RELENG_6_0 or 5.4 (RELENG_5). The server will only be doing postgresql 7.4.9. Is anyone running postgresql with 8 GB RAM or more on 6.0? Our current (and slightly smaller hardware-wise) db-server is running RELENG_5_4 but I'd like to get the improved smp-, disk- and network-related improvements in 6.0. regards Claus
