Another really strange ERX issue - I've bricked 2 ERX-SFPs

Now that the bi-directional iperf problem has been reproduced I've stumbled across another strange and in some ways more worrisome issue. (If I keep this up I can imaging the Ubnt devs will start groaning when they see my posts...)

I have now bricked two brand new out of the box ERS-SFPs by a) upgrading the firmware to V1.9 and b) loading a config. (The config, very lightly edited, is below. I can send the config .tar.gz file if someone at Ubnt wants it.)

Hard(!) to believe that simply loading a config can produce this sort of result. I had to research how to use the serial port pins on the units so I could see the console output while the units boot.

It's not pretty:



I've verified that my serial port setup works by testing it on a functioning ERX and ERX-SFP.

Baud 57600, 8N1. 

I've tried different terminal programs, characters sets (UTF-8, ASCII, etc) but so far had no luck ungarbling the console output of the bricked units.

Though, based on what is readable from the console, it looks like something has gone terribly awry.

I have attempted to use the reset switch to bring the units back but with no luck. I have tried a) letting the units power up and then pressing the reset button, and b) pressing and holding the reset button while power is applied.

Finally, my issues smells a bit like the issue docholliday encountered, at least the config loading part. See: ER-X v.1.9.0 L2TP fails if IPSec offloading enabled.

Thoughts or ideas (besides RMa'ing the units).
