编译最新的2.6.31，启动提示 pci 0000:02:00.0: BAR 0: no parent found

[karv]

下载了最新的kerne2.6.31,编译后能正常启动，但启动有信息提示，具体为：

帮忙看看，看是内核配置时，哪个项目选错了

[karv]

新内核用起来，初步感觉倒是正常，该驱动一起的设备都能用。 framebuffer好像不怎么支持，其他倒还好，就是不知道这个信息提示是什么情况。

环境是：ubuntu9.04 Benq S41本本

[karv]

下载的kernel版本为stable: 2.6.31

[ubuntu_fang]

编译运行正常，除了apparmor模块不能正常加载，其他都正常！

BAR 6: no parent found for of devic

这个问题，我这里也存在。

在 ali 主板上面的 ide 硬盘，会报 dma 的错误，然后硬盘灯常亮，稍后系统无法动弹。

[karv]

这个patch好像并没解决问题 只是把错误提示隐藏了。

而且他那个 patch 在 pci 0000:01:00.0: BAR n （不是6时）: no parent found for of device 时，也就不奏效了。

我这样修改的：
drivers/pci/setup-res.c 的 113 行，修改 dev_err 为 dev_warn 。嘿嘿。

另，8139cp 的驱动，我发觉也有问题。同样，在 2.6.30 上此驱动也没问题。也是在我的 ali 主板的机器上。

不能自动获得 ip 。即使手工指定 ip ，也无法连通。

而且 ifconfig 可以看到此网卡。指定 ip 地址后，ifconfig 显示也正确。
