BCM57788 running in OS X 10.7.2 using BCM5722D (1.0.3) kext - connected at 1000Mbps

Under load (large file transfers > 5GB), connectivity randomly stalls for varying periods of time, then resumes.

Video streaming of m4v (x.264) files via iTunes to Apple TV 2 does not work at all. ATV2 sees the library, successfully pulls the file listing from it, and initiates streaming session fine, but playback dies after a second or two.

Exact same files will stream successfully with no issues from a G5 and from a Windows 7 box running the same level of iTunes, so it isn't a media problem. It's a connectivity problem.

Any help appreciated. Please let me know if you need any specific information from this install (logs, dumps, etc.) and I'll be glad to provide them.
