Hello William,

Thank you for you positive report and kind words regarding the ELRepo
Project -- it is always nice to read of a person's success.

In this case I think it is important that you have posted here, on the
Scientific Linux m/l, so that your issue with the atl1c driver (part
of the distributed kernel package) is recorded. As the SL kernel is
identical to that from upstream and never modified (apart from the
"branding" of the kernel modules), it would be worthwhile you opening
a bug report against the atl1c driver from the current kernel in the
Red Hat bug tracker [1].

Regards,
Alan.
