Is this with USB hard drives or solid-state memory? I've not had any
problems with USB hard drives -- maybe I'm just lucky. Flash keys on
the other hand are a constant problem, although I suspect that's just
down to a mixture of poor treatment and very cheap parts.
I will of course be doing some intensive tests before committing any
valuable data to the system.
That is when I work around this bug which I found when trying to
install CentOS today:
(Despite what the bug report says, installing RHEL hits the same bug).
The problem is that the Geode LX processor identifies itself as an
i586 (not i686) and Red Hat don't build i586 kernels any more.
However it is reported that i686 kernels work just fine -- assuming
you can install them.
