In some testing tonight, the wakeups appear to be from kjournald, perhaps on the order of the atime updates. When I remount my / and /boot filesystems with noatime the very frequent writes go away. Now I only see writes every 20 seconds or so, caused by various parts of software that I'm trying to track down. I think it's really two things going on. 1) bioses are setting the harddrive to be very aggressive about parking, and 2) we're waking up the disk /way/ too frequently. If anybody would like to help me track down causes of 2 and file bugs, that would be awesome! -- Jesse Keating Fedora -- Freedom² is a feature!
