 This is still an issue with 5-current. I have no patch for the kernel
 bug,  but there is
 a quick userspace workaround. Since unmounting ext2 before shutdown
 works
 I inserted the following script into /etc/rc.d for auto-unmount during
 shutdown.
 This bug could bite quite a few,  it should be documented in the 5.3
 ERRATA!
