Hello,
I'm sorry you're having crashes since installing our NIC. Thank you for the data. I haven't had a chance to review it carefully yet, but it looks to me like the crashes have us in the stack sometimes and sometimes not. I need to do a bit more research and will need some more information. Can I get an ethtool -i eth# for the device and also lspci -vvv for the platform its installed on.
If you open an issue at SourceForge we will have a place to keep the logs.
I will research this a bit more and get back to you tomorrow my time.
Thanks,
Carolyn Carolyn Wyborny Linux Development LAN Access Division Intel Corporation
