 Robert,
 
 Thanks for taking this.
 
 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: <NatSemi DP8381[56] 10/100BaseTX> port 0xa400-0xa4ff mem 0xd5800000-0xd5800fff irq 9 at device 9.0 on pci0
 sis0: Silicon Revision: DP83815D
 miibus0: <MII bus> 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.
