Description Vasily Ivanov 2010-10-20 06:00:20 UTC 
Shortly after bringing up igb interfaces system panics. Screenshot: http://pix.academ.org/img/2010/10/20/35b6dd863e7099555ed84a616a97f0bb.jpg

This by far happened only with MSI-X enabled (default).

Hardware is SuperMicro X8DTL with dual Xeon X5650 and Intel Pro/1000ET QuadPort.

Fix: 

Turn off MSX-X in /boot/loader.conf : hw.igb.enable_msix=0

I have the same problem.
Please comment the lines in your /boot/loader.conf and run your tests again.

#hw.igb.rxd=4096
#hw.igb.txd=4096
#hw.igb.enable_aim=1

Best regards,

This doesn't seem to happen on my machines (I have almost identical SM hardware) on fbsd8 and fbsd10.  Is this still happeneing for you?

I did a quick pass but if you are getting this email it might be worthwhile to double check to see if this bug ought to be closed.
