We recently upgraded some of our HP blades and bridge networking stopped working with the the 3.2.0-31 Ubuntu 12.04 LTS Kernel and the be2net driver. I've tested a number of kernels and distros both with and without the be2net driver and I can definitively say that the 3.2.0-31 does not work.
I have confirmed that the following Ubuntu version and kernel work on the same HP blades with the be2net driver.
The only combination that does not work is the be2net driver and the 3.2.0-31 kernel. I have tried the proposed "solution" of configuring the bridges via /etc/network/interfaces with no luck.
Further testing with tcpdump reveals that the underlying physical interface is receiving the packets but they do not appear to be making it to the bridge.
I am happy to provide any elements of the configuration as well as tcpdumps or anything else that might be of assistance.
I'm not entirely sure this bug is invalid.
