[Soekris] CompactFlash Card I/O error

[Roberto Jose Roque Paz]

Hi Jeff:

    In this case, there are a couple of things that get my attention:
a) The Flash Cards given me that problem are relatively new, and there are 3
or 4.
b) If there is a few bad blocks in the flash, why a reboot momentary
"solves" the problem? (and in every reboot the problem presents not
necessarily with the same file).

   What really gets my attention is that the problem happens with reading
operations (writing is disabled, because the partition is mounted
read-only).

   Of course, the usual suspects in this kind of trouble are disks, and I
don't ignore that, but I'm thinking maybe this time there is another reason.

    Heat appears not to be an issue here.

    Tank you anyway.
