Hi Keir,
I found that xen-unstable reported APIC error on my AMD
systems. Please See the output below. I was able to trace this issue to
changset 21407. One observation is that this error only happened to credit
scheduler; but not on credit2 scheduler. It might be related to set_timer() re-arrangement
in changeset 21407. BTW, Xen is still able to bringup 8 cores correctly. So this
error is one-time deal.
Thanks,
-Wei
