I tested again with an up-to-date HEAD kernel on the 4-6282 server.
I've scp'ed 29GB of data, containing both small files (src and pkgsrc trees)
and large ones (xen disk images). No problems.

Could it be related to some BIOS settings ? I don't remember the details;
I think I just disabled the on-board IDE controller. Console is on
com2 (which I had to enable in the kernel) if that makes a difference.
The network controller is:
wm0 at pci2 dev 0 function 0: 82576 1000BaseT Ethernet (rev. 0x01)

connected to a 100Mbs switch. Disk controller is:
mpii0 at pci1 dev 0 function 0: vendor 0x1000 product 0x0072 (rev. 0x03)
