Dave, any progress at > your end? I turned on kmemleak and was able to reproduce this on a second reboot, but it went most of a workday before I noticed it had leaked a bunch. Unfortunately, kmemleak didn't help at all. It found a few small things that _may_ be leaks, but nothing to account for this _massive_ loss. I'm stumped so far. My next step is to add some logging to at least see if this is a gradual thing or it happens all at once, and maybe figure out what the heck I'm doing to trigger it. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
