You've not said which kernel stack you're using (Ubuntu LTS releases have two kernel stack choices), have you tried using the other kernel stack? (you can have both installed, with you selecting at boot which you want to use; https://wiki.ubuntu.com/Kernel/LTSEnablementStack) *Note: I have no idea/experience with your issue, thus this generic option as a workaround until a better comes along*

Help the unilingual among us by prefacing your commands with `env LANG=C` so the results will be in English.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
