I haven't fired up my 6501 to check the exact CPU model (...anyone want to buy it? It's of no use to me since Soekris never released the information needed to work with the FPGA), but I wonder if this could possibly be what's going on with them: https://www.theregister.co.uk/2017/02/06/cisco_intel_decline_to_link_product_warning_to_faulty_chip/

Dries,

        The net6501 seems to have this sort of problem, and it’s fatal.  At 
some point your box will likely stop booting entirely.  If you are within the 
warranty period, then Soekris is good about honoring the warranty.  Outside of 
warranty, you can get a new 6501, or something else entirely.  The root cause 
of death is not well understood, at least not by anyone outside of Soekris.  
There does not seem to be a cure.  The 5501 by comparison seems almost 
impossible to kill.

    ED.

Dear Soekris wizards,

I have a net6501 soekris device and it has a strange issue: when the
device is working correctly and I reboot, then it doesn't start
anymore: the red error led stays on and there's no output on the
serial port. A reset by pressing the reset button or a reset by
disconnecting and connecting again the power source does not make a
difference: the device simply does not start anymore. The only thing
that still works is the uManager Monitor that I can access with '+++':
I can even upload the latest rom and issue commands like 'power cycle'
but in the end to no avail: the regular bios/pxeboot/os does not
start.

If I keep the device unplugged from a power source for +/- 8 minutes,
then it does start again and everything works like it should.

The device has been running uninterrupted for years without a reboot
in the 19" case with built-in power supply that is sold by Soekris.
I've also tried now with some other 12V power supply but it doesn't
seem to make a difference.

Do you maybe know what could be the problem? Any suggestions on what I
still could try or how I might be able to solve the problem?

Kind regards,
Dries
