You can't sucessfully load a module from tasklet because tasklet's run in softirq. You need to use a work queue (or other mechanism) that runs in process context. Loading a module will require accessing disk, and that can only be done from process context. Your whole scheme is pretty daft, because it will be slow and you might as well have the module already loaded. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
