>Description:

The following panic can be triggered on 5.1/i386:

        panic(... 
        __kernassert(...
        tmpfs_rmdir(...
        VOP_RMDIR(...
        sys_rmdir(...
        syscall(...

I will try to append a better trace later.

NB: The same machine was previously running -current with the exact same
    setup, so it can be concluded that this has been presumably fixed in HEAD.
