开启KMS后启动卡死

dkeehl

intel显卡。内核版本2.6.30.1
开启KMS以后启动时会卡住
控制台显示的信息，除kms相关内容以外，跟普通的启动一样。没有错误信息。只是会停在
kernel: ahci 0000:00:1f.2: flags: 64bit ncq pm led clo pio slum part
就不往下进行了
关闭KMS后可以正常启动
迷惑中，求解

以下是显卡相关的内核配置：

这个我知道。我想问的是有没有办法让KMS正常起来

lophyxp

将
# CONFIG_DRM_I810 is not set
# CONFIG_DRM_I830 is not set
m试试。

貌似我只找到了gentoo-sources-2.6.30-r1的说，没有见到2.6.30.1。

nonplus

1. equery l gentoo-sources
   
2. * Searching for gentoo-sources ...
   
3. [IP-] [ ~] sys-kernel/gentoo-sources-2.6.30-r2 (2.6.30-r2)

复制代码

好像是led方面缺少了某些东西导致
同样是intel显卡（GM945的），能正常启动
附上我的，你自己改了试试看能不能启动
PS：懒得看config.....还不如make menuconfig截图上来简单得多

暂时解决了
把i915编译成模块，init时用modprobe加载，之后一切OK。原因不明。
感谢各位的回复
