Title: kernel BUG at fs/ext4/inode.c:2679! Status in linux package in Ubuntu: Confirmed Bug description: I started seeing this bug in Ubuntu 18.04 running VMWare Workstation Pro 14. After upgrading to Ubuntu 18.10 and VMware Workstation 15 the bug still appears. I started to ask questions on the VMware Community, https://communities.vmware.com/thread/604705. Because I had some additional time to troubleshoot I am also noticing that this bug is being reported on other Linux Distributions notably: https://bugzilla.redhat.com/show_bug.cgi?id=1662314 Conditions to reproduce. Laptop is running 2 NVMe drives with Cryptfs on each drive (unsure if this is related). Running Vmware Workstation Pro 15 with a Windows 10 Guest upon shutting down the Windows Guest a kernel stack strace appears in both dmesg -w and /var/log/syslog. The VM does not gracefully stop.
