Unfortunately I don't monitor precisely kernel version and updates. Hard to say in what state was system prior to current one.
And I don't have strong scenario to reproduce this issue. But it hit me be several times. I know cases in with it looks like appear. Switched to upstream kernel. So far so good. Will continue to monitoring. If I will not be able to reproduce this issue during next week then I will mark bug with 'kernel-fixed-upstream'. -- 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/1626517 Title: Access to some folders hangs and in dmesg see kernel BUG report Status in linux package in Ubuntu: Confirmed Bug description: Probably freeze during access to folder caused by kernel BUG at /build/linux-BvkamA/linux-4.4.0/fs/namei.c:2562!
