I upgraded one of our new 3750x's to 15.0(2)SE5 from 12.2 and now I am seeing the following message in the log
My testing of version 15.0(2)SE5 lasted for about 15 minutes. And the entire time was attempting to ROLL BACK. When I loaded this version on a 3560, the CPU spiked that I lost connectivity (remotely and console). I will NEVER recommend any sane person to use 15.0(2)SE version except for 15.0(2)SE4.
For 3560/G/E/X and 3750/G/E/X, I will recommend 12.2(55)SE9 as one of the most stable codes Cisco's ever published. For 3560G/E/X and 3750G/E/X (with 32 mb flash), you can also try 15.0(2)SE4.
PS: Don't be tempted to use 15.2(1)E train either. It's the worst IOS train I've ever seen.
