[Kernel-packages] [Bug 1818501] Re: kernel BUG at fs/ocfs2/alloc.c:1514
Unfortunately we don't have a dedicated test system here, and I don't really want to test this on the production system... I can confirm that upgrading to the HWE kernel (4.18, which contains the patches) seems to solve the problem. -- 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/1818501 Title: kernel BUG at fs/ocfs2/alloc.c:1514 Status in linux package in Ubuntu: Confirmed Bug description: The current bionic kernel (4.15) contains a known bug in the OCFS2 distributed filesystem, which can cause all nodes (!) of a redundant cluster to crash.

Adding log with apport-collect files is not easily possible due to our security setup, but should not be necessary because all information can be found in the linked debian bug report.
