Comment 10 for bug 658955

Interestingly, while it failed in 3.2.0 (that's what the above patch is against) the motherboard boots out of the box with 3.3-rc6. There's a new DMESG error however on the first and subsequent resumes:

[ 695.000381] Enabling non-boot CPUs ...
[ 695.000381] Booting Node 0 Processor 1 APIC 0x1
[ 695.000381] smpboot cpu 1: start_ip = 9a000

which repeats for CPUs 2 & 3. Full DMESG attached. Searching LKML reveals that Robert Richter from AMD has written a bunch of driver code in this area, but this error appears to be more than the expected AMD "bug" notices for this chipset family. Still, the system is operating normally and suspends/resumes OK.
