linux - EEPROM : uevent generated infinite times in linux kernel 4. 4.0

Question

我正在使用运行 Linux 内核 4.4.0 的 Ubuntu 16.0.4。我的板上连接了几个 EEPROM over i2c 适配器。当我插入 eeprom 模块时，我在 /var/log/syslog 中看到不确定的 uevent 消息:

我检查了所有 eeproms 芯片的 sysfs 设备树和设备节点都创建良好。

我不明白为什么 EEPROM 芯片的 uevent 还在生成。

有人知道为什么吗？

在内核配置中禁用 i2c 核心调试(CONFIG_I2C_DEBUG_CORE 未设置)。
