Jeff, This looks BZ 463716, stack trace is identical, it only occurs if we configure the sata controller in IDE mode instead of AHCI mode. Is it possible that the sata controller on this system is configured in IDE mode?
David, Absolutely that could be the case. I wouldn't be surprised if we have some systems in RHTS set like that on purpose to catch these kinds of things. The only way I would know for sure is to actually go through the BIOS and take a look. Is there any way to tell from the boot log? http://rhts.redhat.com/testlogs/30842/111282/946920/boot.messages If not let me know I will go through the BIOS.
Thanks Jeff, boot log confirms it is the same problem as BZ 463716 so I will mark this as a duplicate. *** This bug has been marked as a duplicate of bug 463716 ***
