New test build here, r3764. All the usual stuff included.
I have been trying hard to crash it today by not turning off the offloading features and by running SQM QoS. So far, so good.
Also, VLAN tagging should be fixed. See this and this.
Just got another stack trace so testing now with all offloads off.
