(Which was changed recently) Firstly, I have to say I don't see this in the mainline tree, so could you try that with your setup just to verify (git head at 2.6.29-rc6). If this holds true, there must be a bad patch in the -rt tree. You should be able to diff scsi_lib.c to see if there's something missing. Finally, there are one or two drivers (SCSI target) that do their own buffer management, so what drivers are you using?
