mtrr: your processor doesn't support write-combining导致启动慢？

gflei

Dec 22 23:42:02 debian-gflei gconfd (egov-2996): 正在启动(版本 2.8.1)，pid 2996 用户

上面是/var/log/messages中的部分内容

因启动很满，看了上面的信息，能确定是因为 mtrr: your processor doesn't support write-combining
引起的启动慢吗？

这个错误如何解决？谢谢！

再看了一下/var/log/syslog中的信息：

看到底是哪个执行慢了？

d00m3d

CPU 是啥？内核是自己编译的？

gflei

是在虚拟机上跑的，
AMD Sempron 2600+
内核没编译过

再仔细看了一下log，这应该是usb设备的问题。

刚开始可能因为插有移动硬盘，现在拔掉了移动硬盘，在后来的几次启动中就比较快了。
