Didn't I cover this in the announcement? It appears that making smbfs depend on CONFIG_BROKEN doesn't seem to be enough to get it removed from .config's by make oldconfig. d_validate() is bad, trust me on this one. Is cifs a good enough replacement for you? On Sat, Dec 13, 2003 at 11:45:26AM +0300, Yaroslav Rastrigin wrote: > 2. With 2.6.0-test11 vanilla, suspend-to-ram/suspend-to-disk was > working nicely.

I'll have to try non-APM -based suspend for this. -- wli
