It's mostly the PAE pmap-related bug (reverted before 4.1-release), but I think there is also some problem with the non-ACPI irq tables with the BIOS shipped with the motherboards, I think this is also fixed on the newer BIOS. Run them on 4.1 or -current with either ACPI enabled or latest BIOS and they should be happy. Mine (single-core) are much better with bsd.mp for the APICs. I have a bunch of these, mostly as routers (bgpd/ospfd which are great). I prefer them to Sun X2100 after I got those problems fixed (PCI slot which accepts ebay'd fibre cards, two half-decent NICs onboard rather than one and an nfe, and I found them easier to buy). > em0 at pci2 dev 1 function 0 "Intel PRO/1000MT (82546GB)" rev 0x03: irq > 9, address 00:04:23:d0:93:60 > em1 at pci2 dev 1 function 1 "Intel PRO/1000MT (82546GB)" rev 0x03: irq > 5, address 00:04:23:d0:93:61 If you have any problems with the em(4), try jumpering the pci-x for 66MHz rather than auto, there's definitely some problem with the newer quad cards and 133 on these boards, which might apply to the other cards. There is also a jumper you can do to force power-on after power failure, which is very useful if they're remote.
