[Bug 1812086] Re: kernel BUG at /build/linux-vxxS7y/linux-4.15.0/mm/slub.c:296!
That's a different stack trace and looks like a different problem that just results in the kernel dying in the same place. And 4.18 is no longer supported. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1812086 Title: kernel BUG at /build/linux-vxxS7y/linux-4.15.0/mm/slub.c:296!

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.
