However, having proper core dumps is needed to debug the r= oot cause. You can try backporting the changes I mentioned previously to your 10.2 ker= nel (you can get by with just the first two for testing) to see if we can get m= ore usaable core dumps to use in tracking down the root cause. If you aren't u= sed to backporting changes I will try to do it in the next day or so (those fix= es should be in 10.3 anyway). Once I've done the backport I can give you a pa= tch to apply to your 10.2 kernel. --=20 You are receiving this mail because: You are the assignee for the bug.=
