Hi, I was going to ask if you have the 2745 bios but I see that you do so that's cool (it had several Marvell updates). I am running Vista 64 with an x6800 and 4G and I successfully did a 'clean' install but I only have a 4 drive matrix raid setup. They are all on the ich7r controller as 4 500G Seagates 7200.10s; I configured it as two volumes with c: as a 400G raid 0 and d: as a 1.2G raid 5 configuration (very nice, very fast). The installation went fine, without any issues or hiccups and it has been very solid since (today I just installed the latest raid drivers). I haven't tried anything on the Marvell controller yet (I still don't fully trust it so I'm saving it for esata and optical drives only).
I looked at the MS KB and they had nothing for Vista (32 or 64-bit). The only thing that was referenced at all was with regards to networking and most of it was for W2k3 (Vista's immediate daddy). I am running gigabit on a standard home-type network (linksys) and it works fine; I don't know what you have going for networks. If you look at the KB articles, there is one that gives a reasonable 'cause'...
This problem can occur if a Layered Service Provider (LSP) has been registered by using a Winsock catalog and the socket is canceled. Because of a thread synchronization problem, Winsock occasionally tries to free memory structures two times. In particular, you may experience this problem if Citrix Metaframe is installed and many users log on and log off by using Terminal Server sessions.
If you do want to continue trying to install Vista 64 (and if you don't mind a suggestion or two), I think you should try to drastically dummy-down your system until you figure out the problem. Perhaps an initial go with maybe no networking and with a much simpler 4-drive raid configuration (I know that works
). Based on the 'cause' statement (above) you may want to totally unplug your eithernet cable altogether, I am suggesting that you really dummy-down your system until you determine the problem. You can always hook up the lan and add another volume or two later.
Best
