This is likely due to commit 6069e3e927c8 ("USB: cdc-acm: untangle a circular dependency between callback and softint") which had a bug that was just fixed by commit a8b3b519618f ("USB: CDC-ACM: fix poison/unpoison imbalance"). You can try applying the latter yourself but it will otherwise show up in stable soon. Johan --=20 You may reply to this email to add a comment.
