Bug ID: 211959
Summary: vfs: kernel panic
Product: Base System
Version: 11.0-RC1
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: pku...@anongoth.pl
I get a kernel panic when moving files from phone to HDD.
It happens after the upgrade from 10.3-RELEASE to 11.0-RC1. Seems to be related
to VFS fixes which were committed recently. Unfortunately, I didn't use 11.0
before those fixes, so I can't say for sure.
