2.6.4-rc1 & rc2 Oops

2.6.4-rc1 & rc2 Oops

[Jeff Lightfoot]

The following Oops happened in 2.6.4-rc2 and one almost exactly
like it happened in 2.6.4-rc1.  It seemed random otherwise I'd try
to narrow it down.  My last kernel before those was 2.6.2-mm1
and I hadn't seen this.  This current one came at about one
day and 12 hours of uptime.

Let me know if tons of other info would be useful.

Basic:
vendor_id	: AuthenticAMD
