We have 30 connex400xm purchased in August 2007 and field upgraded to
U-Boot 1.2.0. (build 1536). Surprisingly, even after the suggested
u-boot upgrade, almost all of them have duplicate serial numbers
(/proc/cpuinfo) with 2 or 3 or 4 others among the 30 gumstix.
According to this document
the newer boards (after March 2007) are supposed to have 'guaranteed
unique serial number'
and the older ones with update U-Boot should have "a more robust and
less collision-likely MAC generation algorithm".
