It seems I had turned on tcp4csum-tx on the gem0 interface (and I am
using NFS with option -T). Turning that off again, seems to fix the
issue.
So looks more like a gem driver bug. Hardware is:
gem0 at pci0 dev 5 function 1: Sun Microsystems ERI Ethernet (rev. 0x01)
gem0: interrupting at ivec 321d
ukphy0 at gem0 phy 1: OUI 0x0006b8, model 0x000c, rev. 1
ukphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
gem0: Ethernet address 00:03:ba:12:67:05, 2KB RX fifo, 2KB TX fifo
Ifconfig output (now again without tcp4csum-tx):
gem0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
capabilities=800<TCP4CSUM_Tx>
enabled=0
address: 00:03:ba:12:67:05
media: Ethernet autoselect (100baseTX full-duplex)
status: active
