Thanks for your reply, Erich.
I've been successfully booting the target machine from a Bering-uClibc
v3.0-Beta2 CD and reading/writing config to USB flash for 2+ years and
it continues to boot properly with that config.
From the Bering-uClibc v3.1.1-Beta2 setup that's giving me trouble:

Thanks for your reply, Erich.
I've been successfully booting the target machine from a Bering-uClibc
v3.0-Beta2 CD and reading/writing config to USB flash for 2+ years and
it continues to boot properly with that config.
