I'm currently getting snow on my 2010 27" iMac in target display mode connected to my 2011 Mac Mini Server daisy chained to a LaCie Thunderbolt Little Big Disk. It occurs in both Windows 7 and OSX Lion. The issue is sporadic and at times the display is stable. No issues with the iMac display in normal mode or without the daisy chain.
Any ideas would be appreciated.
