PVE直通SATA控制器硬盘无法休眠！

PVE直通SATA控制器硬盘休眠几秒就唤醒，不断重复。把log文件挂载到内存也没有用。
日志不断提示：Internal disks woke up from hibernation.

这个问题我之前也发现了，日志信息还是比较清晰的，比较好解决。
其实这个问题是redpill驱动引起的，在硬盘休眠的时候系统触发了HDIO_DRIVE_CMD命令，而redpill驱动对这个命令处理失败以致写了日志，日志信息被追加到了 /var/log/messages 和 /var/log/kern.log 这两个文件，而这两个日志文件是属于在硬盘分区里的，因此系统需要重新唤醒硬盘来写这些日志文件。

解决办法1：
    修改redpill驱动的smart_shim.c文件，把第684行的 pr_loc_err("Expected to copy HDIO_DRIVE_CMD header of %d bytes from %p - it failed", HDIO_DRIVE_CMD_HDR_OFFSET, buff_ptr); 这行代码删掉或者注释掉，然后重新编译redpill引导即可。
   
解决办法2：
    修改 /etc.defaults/syslog-ng/patterndb.d/message.conf 和 /etc.defaults/syslog-ng/patterndb.d/kernel.conf 文件，把 /var/log/messages 和 /var/log/kern.log 日志文件分别都设置到 /tmp/messages 和 /tmp/kern.log ，然后重启系统即可。
    最好也把 /etc.defaults/logrotate.d/syslog-ng 里的 messages 和 kern.log 路径也做相应的修改，否则这两个日志文件的大小可能会无休止的增长。

物理机安装也是硬盘刚休眠不转了  过一两秒又开唤醒了。。。3615  918  不同的三台机器都是一样的情况，，

我这物理机安装也没见硬盘会休眠。。。
