I have a problem with suspend to ram. My notebook is a sony vaio fs315m with gpu nvidia geforce go 6400 turbo cache. My OS is gnu/linux gentoo kernel 2.6.19-suspend2 patched by gentoo and latest drivers of nvidia (9746).
Suspend to disk works perfectly but suspend to ram give a black screen on resume and the system crash (it does not reply to any ping or ssh session). It is strange that with nvidia drivers 8774 any suspend works (suspend ti disk works perfectly, suspend to ram fails sometimes).
ps: sorry for bad english
