Sorry, I don't know how to post the tags: kernel-fixed-upstream-v4.3-wily I don't see anymore the Corrupted low memory. There is another way to check this that just see the syslog? ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1507091 Title: Corrupted low memory on Ubuntu 15.04 Status in linux package in Ubuntu: Confirmed Bug description: I have had a lot of freezes on my laptop, and I'm trying to figure out what is the reason because just have like 6 months of bought.
