ESXi 5.5, Dell R815 new BIOS and PSOD TLB ACK invalidate

I'd like to hear from people who have observed PSOD's of type "TLB Ack Invalidate" on Dell PE R815 servers (or similar). I've personally observed 12 occurrences of this across multiple Dell servers with BIOS 3.2.1 over the last several months. Now, there is a new BIOS version 3.2.2 with references a fix for a known stability issue when using the R815 with ESX and AMD 6300 series processors. Is this something that has been widely observed or have I just been unlucky to have run into so many issues? If you have seen it, is there any publicly available information about this known issue?

VMWare support documents state that this type of PSOD is related to a hardware issue. When I hear hardware issue, I think hardware failure, but the BIOS update indicates it is more to do with hardware function than failure. I'd appreciate your thoughts about how to categorize this sort of problem.
