Just want to confirm that the current U-Boot, 2014.04, still has problems

Did you un-write-protect the board eeprom?
Regards,
Pulled pin 7 (WP) to ground, yes. I've made the changes to U-Boot to skip
the check of the ID EEPROM and I'm now, through U-Boot, trying to program
the baseboard ID EEPROM with a proper signature. Linux version
3.8.13-bone35.1 starts to boot, but issues a Kernel Panic as seen here in
the console output:
Odd, it's working fine here: ( 3.8.13-bone47)

This is our custom board and I'm trying to eliminate any unknowns by getting
a good ID EEPROM signature setup up.
So, is U-Boot good to go, or should I get an older version from a BBW to get
the EEPROM programmed?
Is this a clone of the BBB? and using a 1Ghz cpu?

Regards,
Yes, a subset of the BBB based on the reference design from Gerald. No,
we're running the 720MHz version of the AM335x, but are using the
TPS65217C and the DDR3 memory like the BBB.
Looking at the http: reference above, seems that the kernel WILL boot
without a proper ID EEPROM signature, so I guess I don't need to worry
about that as being the Kernel Panic source. I guess I'll keep digging
into our hardware.
Thanks,
Ross
