Now I can't without the em0 interface stalling :-( On a guess, I tried reverting SVN r335303 but that didn't help. em0: <Intel(R) PRO/1000 Network Connection> port 0xf080-0xf09f mem 0xf7e00000-0xf7e1ffff,0xf7e39000-0xf7e39fff irq 20 at device 25.0 on pci0 em0: attach_pre capping queues at 1 em0: using 1024 tx descriptors and 1024 rx descriptors em0: msix_init qsets capped at 1 em0: PCIY_MSIX capability not found; or rid 0 == 0. em0: Using an MSI interrupt em0: allocated for 1 tx_queues em0: allocated for 1 rx_queues em0: Ethernet address: f0:1f:af:66:95:7e em0: netmap queues/slots: TX 1/1024, RX 1/1024 em0: link state changed to UP [ initiate "zfs send" ] em0: TX(0) desc avail = 41, pidx = 172 em0: link state changed to DOWN em0: TX(0) desc avail = 1024, pidx = 0 em0: TX(0) desc avail = 1024, pidx = 0 .. ad nauseum .. "ifconfig em0 down; ifconfig em0 up" doesn't help. Any hints? imb
