We’ve recently purchased an Edgeport/416 unit and are experiencing some issues running the unit in a Linux based environment.
Initially after plugging the device in, the device seems to work as I would expect then at some point it would appear as if the device spontaneously resets itself.
I see some flickering amber lights, followed by a single red light flash, then back to flashing green.
The unit appears to repeat this cycle every few minutes (no defined interval, but ranges from a dozen seconds to a dozen minutes.)
We have the newer TI chipset version of the 416 (P/N 50001359-01), and have tried running this in four different Fedora release versions:
- FC12 i686 : kernel 184.108.40.206-175.fc12.i686.PAE *
- FC14 x86_64 : kernel 220.127.116.11-91.fc14.x86_64
- FC15 x86_64 : kernel 18.104.22.168-26.rc1.fc15.x86_64
- FC16 i686 : kernel 22.214.171.124-26.rc1.fc15.i686.PAE
All of which give the same results.
The FC12 system is currently running with 3x Edgeport/8 devices with no issues (also based on TI chipset/using the io_ti driver.)
To verify the hardware, I plugged the unit into a laptop running Windows XP SP2, and installed the drivers. After a couple resets the driver installation completed and the device seemed to come up fine with the edgeport device utility showing all of the ports. A quick local-loopback test showed no issues, and then I left the unit plugged in for a good 35minutes or so constantly monitoring the state of the LEDs - they remained green (slowly flashing) the entire time.
I assume this means that there isn’t anything wrong with the hardware itself, so I’m at a loss as to what the issue here actually is (other than the device not being properly supported under Linux/Fedora.)
For reference, I’ve attached an excerpt of the /var/log/messages file with messages related to the device.
