Comment 4 for bug 147464

I can confirm this. I have a server that backs up files from other computers to a NAS device (it retrieves the files through CIFS and stores on the NAS through NFS). After a bit of heavy copying, the ethernet adapter locks up (the system is responsive, though I'm not sure because it's headless, I just see log entries), but the ethernet device will not accept or emit packets. It's a pretty serious bug. I worked around it by setting large packet sizes and it worked for a bit, but now it's back to broken.
