Lee, I've read the support-forums thread, and am in a similar situation. I've been running 7.6.100.0 since holiday break, and based on the bugs in the thread, I'm inclined to request access to the engr. build "just in case". My network is not as large as yours (~8500 simultaneous & 25K unique devices/day) but it's hard to read something like "Broadcom chipsets may have trouble associating or may experience traffic hangs..." and not assume I have users hitting this. I have not heard complaints, but that doesn't mean much.
My need for 7.6 (more specifically 7.5+) is features. I don't anticipate having 3700's for about another 60 days. In conclusion, I've given you no useful information but will update if I do ever get a direction on that MR code ( I'll actually be at the EBC tomorrow, so will try to corner someone into getting a sense of severity on these 7.6 bugs).
