[Server-devel] Active Antenna woes

Sorry it took so long to get back to you on this.  It's been a rough  
week.
Are you still having problems ?

Does the same think happen when you attach the antennas after the
server is booted ?   Take a look at dmesg after doing this.

I'm having trouble

The tx_watchdog timeouts are due to problems in the
Marvell firmware/hardware.   A rewrite of the driver stopped this
problem from crashing the driver, but the underlying problem is still
happening.

Regards,
John
