There is a regression in 11.2-RC3 that effects the igb driver for Intels C2000 SoC I354 Quad GbE Controller Supermicro A1SRi-2558F http://www.supermicro.com/products/motherboard/Atom/X10/A1SRi-2558F.cfm This server has run 10.x and 11.x fine up till 11.2-RC3. PROBLEM: with 11.2-RC3 the server boots and gets a network connection to the cable modem, but the interface (igb0) resets every 4-8 second. The reset time appears to be related to network load, but reset withing 10s with next to no traffic. I did try swapping cables, but with no effect. With each reset the interface successfully obtains an IP address via DHCP, works for a few seconds and resets. Restoring the server to 11.1-RELEASE-p10 resolves the problem. Any suggestions? -- David Samms
