First off, the previous message I wrote (about similar problems with samba) might in fact also be caused by NFS - samba is running on this server, but it was configured to serve a directory which itself is served by amd(8) on this server. Now to your questions: device/driver (grep sis /var/run/dmesg.boot): sis0: port 0xa400-0xa4ff mem 0xd5800000-0xd5800fff irq 9 at device 9.0 on pci0 sis0: Silicon Revision: DP83815D miibus0: on sis0 sis0: Ethernet address: 00:40:f4:1a:42:ba sis0: [ITHREAD] sis0: Applying short cable fix (reg=f4) sis0: Applying short cable fix (reg=f5) mount: It is what amd(8) instructs it to be, and from running tcpdump I believe it is over TCP.
