Weeeeeellll... not quite. It will not disable all features of laptop-mode-tools, but it will disable the remount on power loss, yes. And that will make the spin-down-the-hard-drive option (a.k.a. "laptop mode") fail to work, because changing the mount options is required if the hard drives need to spin down. You can still use the other modules. Anyway, you could try and report this for the upstream kernel at: http://bugzilla.kernel.org/ They should be able to debug and fix this! I could do it myself BTW, but since I can't reproduce the problem it's better if you report it and help them find out what's going on. Keep me posted -- I want to know what happens with this, because it definitely isn't nice. :-/ Cheers, Bart -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
