As soon as I say this, I go back and am completely unable to make 2.6.13-rc5 reproduce the issue. *grumble* black magic *grumble* :-D. Cheers, Kyle Moffett -- There are two ways of constructing a software design. One way is to make it so simple that there are obviously no deficiencies. And the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult. -- C.A.R. Hoare
