I was recently trying to fix a Hyper Transport Sync Flood error as described here (http://forums.amd.com/forum/messageview.cfm?FTVAR_FORUMVIEWTMP=Threaded&catid=22&threadid=88140), only difference being I encountered the issue at each startup after installing some Ubuntu updates, including linux kernel 2.6.31-20 which required a reboot. It prevented me from successfully booting into the OS.
Anyway, I tried several recommendations such as manually setting voltage and frequency settings for my memory, and eventually decided to try resetting the BIOS to default settings to try and resolve the issue. Upon rebooting I came across the same "GRUB _" issue at boot that I had months before, which you helped me resolve.
I used the same script you had me use last time to generate a RESULTS.txt file about the boot process. I not yet familiar enough with Ubuntu Linux to be able to understand everything in the text file and was wondering if you could help explain how to fix this? I wasn't aware BIOS settings could affect the OS in this way (other than say boot order).
RESULTS.txt is posted below:
