In conjunction with possibly sub-optimal defaults in other areas (brand new default ubuntu 7.10 server installation, no laptop-mode or anything else unusual), this was causing rapidly increasing load/unload count on the hard drive. Redirecting logging to /dev/null, suggested above as a workaround, possibly coupled with hdparm -B 254 as suggested elsewhere, has reduced the rate of increase of that figure. I certainly consider that the "advanced configuration and power interface" daemon, of all things, writing to a log file several times each minute, thus preventing power saving operations from taking place, when nothing of any interest is happening, is a bug! -- Log output far too verbose https://bugs.launchpad.net/bugs/31512 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
