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.

More information on this bug (including the patch) can be found here: https://bugs.debian.org/cgi- bin/bugreport.cgi?bug=841144 This fix was included upstream in 4.16, so it is included in the HWE stack, but not in the GA kernel. In my opinion this is quite severe bug, because it can bring a whole redundant setup down (this happened to us). This patch should be backported to 4.15. #cat /proc/version_signature Ubuntu 4.15.0-45.48-generic 4.15.18 # lsb_release -rd Description: Ubuntu 18.04.2 LTS Release: 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1818501/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
