Same init scripts, different kernels. Note that the respective update changed /etc/conf.d/alsasound (a local configuration file) to include UNLOAD_ON_STOP="no" KILLPROC_ON_STOP="no" This change by update is not activated by a mere emerge; one needs to incorporate that change with dispatch-conf or an equivalent method. (Or simply edit the file to have these variables set to "no".) > And sure, I could put a comment on the rmmod, in the init script, but > IMO that would be a hack around a _bug_. Which is fine for me. But, > is it worth leaving the issue in the kernel? Is it a kernel issue if a script attempts to unload a busy module, then fails to proceed? I wouldn't think so. But more importantly, is this init scripts related bug really what's happening at your system? Or do you actually experience an entirely different bug? -- Stefan Richter -=====-=-=== -=-= -==-= http://arcgraph.de/sr/ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
