LZ你好，我按你给的方法编译成功，但发现程序的CPU占有率比我用的UBUBUNTU8.04.1的默认内核2.6.24-19上CPU占有率翻了几倍，原来mplayer后台播放音乐只占2%-3%，现在都上10%了，我的CPU才1.6G
编译了几次也没解决，只好来求助了
这个问题还有人磁到过没？？

估计是CPU类型没有选好。

product: Mobile Intel(R) Celeron(R) CPU 1.60GHz
应该是P4Celeron这一项，而且改成别的也是一样的确，有点郁闷了

编过red hat的……没有编过ubuntu的……现在因为某些支持问题，决定试一下。

[gaby]

在http://www.kernel.org/下载也太慢了吧……
应该到http://www.hanwater.lkams.kernel.org/pub/linux/kernel/v2.6/下
楼主写得详细一点比较好，要不然下3个小时都下不完。

还有，楼主为何一定要与众不同呢。ubuntu默认的内核都是放在/usr/src的。虽然没有规定，但是放到别处又有啥意义呢。

[gaby]

今天去编了一通内核，结果发现两个问题：
1，无线网卡要自己装，在编译的时候选了也没用，结果还是用不了
2，我编译内核的目的──读取SONY的卡没实现。我把memory stick支持都编进内核里面了，结果还是读不了。

其他的，我没发现编译内核有啥意义。

为了试用reiser4，重新编译了N次内核。
开始时用了8.04的2.6.24.22的配置文件，编译出来的deb包有上百兆。后来精简后，image包降到7.6兆。
昨天进一步精简，编译出来的image包4.9M，headers包6.1M。安装后的initrd.img为2.7M，vmlinuz为2.6M。
机器是P4D 3.2G，2G内存，945G主板。
试了一下reiser4，打开了压缩选项后，原来的/ 和/home有8.44G，在新的reiser4分区上只占了6.17G，效果还是很明显的。速度也不慢，但也没感觉到比reiserfs快多少，而且在fsck的时候，显示错误较多。试了一下又换回reiserfs了。

以前用UBUNTU 8.04的官方内核时，启动时间一般在70秒左右（从出现grub开始到gnome桌面可用，包含输入用户名和密码登录时间），现在是55秒左右。xp在这台机器上的启动时间也在70秒左右。

processor type and features里关于xen的选项要去掉。。
不然会出错
为了这个我搞了好久。。吐血
默认的设置也挂了。。。更吐血。。
