Time machine stopped after 10.6.1

[MTShipp]

I have 2 Macs. Both are backing up to a 1 TB extreme. Today, the iMac started etting delayed failures while accessing TM. I restarted both the Mac and the TM and now it is hung on "Making backup disk available".

Anyone know what could cause this?

Having the same problem with a Buffalo drive LSH-XH1.0TL. Buffalo's techs are telling me that Snow Leopard made some changes that will require them to do a firmware update for my NAS before I can use it for Time Machine. Anybody have any news on how the updates are going?
