Hi David and tech@, I just tried the patch on a December 28 snapshot and got a watchdog timeout while running iperf. Just the snapshot without the patch survives iperf without a timeout.
The device in question is this one: em0 at pci1 dev 0 function 0 "Intel 82583V" rev 0x00: msi, address 00:03:2d:20:cf:84 This is on i386. Do you need a full dmesg with/without the patch? Is there anything else I can do to aid in debugging? I'd also be more than happy to provide a shell on the router and stand by with a console cable to aid in debugging. -- Gregor
