A downgrade to linux-4.13.12-1 works fine. Looks like a known problem: https://bugs.debian.org/881744 https://www.virtualbox.org/ticket/17267 So this looks like a situation where the 4.14 kernel will effectively eliminate the ability to use 5.1.30. It doesn't look like there will be a further maintenance release of 5.1.X while all initial problems with 5.2 are resolved. So this is an Oracle/4.14 issue. -- David C. Rankin, J.D.,P.E.
