I built a test kernel with commit eb4c2382272ae7 from linux-next. This commit relies on commit d633198088bd9 for the definition of spin_lock_rcu_node and it's corresponding unlock. That commit was added to mainline in v4.16-rc1
The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1802021 It sounds like this bug is difficult to reproduce, but it would be great if the affected customer was willing to test this kernel. Note about installing test kernels: • If the test kernel is prior to 4.15(Bionic) you need to install the linux-image and linux-image-extra .deb packages. • If the test kernel is 4.15(Bionic) or newer, you need to install the linux-modules, linux-modules-extra and linux-image-unsigned .deb packages.
