Did you not notice I have quoted RedHat Bugzilla for these bugs?

Anyway, the last sentence of my original email was somewhat misleading. I meant to say something to the effect that these bugs should be noted in the Known Bugs section of the Release Notes (currently empty).
Also, I was not expecting the Fermilab team to correct the bugs, but was rather hoping that the SL7.2 release iso would include some workarounds so that at least the install would work for all AMD cpus.

Finally, I will recheck the SL7.2 RC once it has downloaded, just in case some workarounds have been included.

Cheers
Bill
