I recently installed OpenBSD-current snapshot onto a box that has an nvidia chipset, including integrated an integrated MCP51 10/100 nvidia network controller.
I cannot seem to get the network to work under OpenBSD, although it worked quite well with FreeBSD. the related bits in dmesg are: nfe0 at pci0 dev 20 function 0 "NVIDIA MCP51 LAN" rev 0xa3: apic 2 int 20, address 00:18:f3:35:6d:d4 nfe0: could not load rx buf DMA mapnfe0: could not allocate Rx ring I tried searching via google.com for anything I could find even partially related to this, but I've come up empty handed. kern.version=OpenBSD 5.6-current (GENERIC) #284: Wed Aug 20 23:07:52 MDT 2014 dera...@i386.openbsd.org:/usr/src/sys/arch/i386/compile/GENERIC -- Chuck Burns Audemus Jura Nostra Defendere
