升级内核，从2.4升到2.6的问题，高手们一定要帮帮忙啊

liuzhijian

我从2.4内核升至2.6后，有几个怪问题，请帮忙看看：
在2.4下添加XDSL联接没有问题，而在2.6下添加就出现如下错误代码：
Component: redhat-config-network
Version: 1.2.0
Summary: TB /usr/src/build/226257-noarch/install/usr/share/redhat-confignetwork/netconfpkg/NC_functions.py:119:rpms_notinstalled:TypeError: rpmdb open failed
Traceback (most recent call last):
  File "/usr/src/build/226257-noarch/install/usr/share/redhat-config-network/netconfpkg/gui/NewInterfaceDialog.py", line 144, in on_start_page_next
  File "/usr/src/build/226257-noarch/install/usr/share/redhat-config-network/netconfpkg/gui/ADSLInterface.py", line 110, in get_druids

  File "/usr/src/build/226257-noarch/install/usr/share/redhat-config-network/netconfpkg/NC_functions.py", line 144, in request_rpms
  File "/usr/src/build/226257-noarch/install/usr/share/redhat-config-network/netconfpkg/NC_functions.py", line 119, in rpms_notinstalled
TypeError: rpmdb open failed
好像是说rpmdb打开失败，这是怎么回事？

还有我重设rpm，出现如下错误代码：
[root@localhost rpm]# rm -f _db*
[root@localhost rpm]# rpm -vv --rebuilddb
D: rebuilding database /var/lib/rpm into /var/lib/rpmrebuilddb.3023
D: creating directory /var/lib/rpmrebuilddb.3023
D: opening old database with dbapi 3
D: opening  db environment /var/lib/rpm/Packages joinenv
rpmdb: unable to join the environment
error: db4 error(11) from dbenv->open: 资源暂时不可用
D: opening  db index       /var/lib/rpm/Packages rdonly mode=0x0
error: cannot open Packages index
D: removing directory /var/lib/rpmrebuilddb.3023

还有在2.4下能正常使用我的U盘，在2.6下就无法找到U盘，我的U口是2.0的，不知道是不是我在编内核时少编了什么？在下第一次使用linux，在研究了数日，实在是没法子了，请大家帮帮我。谢谢了。

如果是自己编译的内核，需要把usb支持编译到内核中去，否则U盘就用不了的。建议再次编译内核时参考一下精华区里的贴子。

可是我把USB中所有能选的都选上了，可还是不行啊。
而且RPM的问题，我在精华贴中找到了答案，要升级RPM，我下了rpm-4.2-1.i386.rpm，运行后，如下代码：
[root@localhost liuzj]# rpm -ivh rpm-4.2-1.i386.rpm
warning: rpm-4.2-1.i386.rpm: V3 DSA signature: NOKEY, key ID 2039b291

这样是不是安装好了呢？一开始指示NOKEY，是什么意思？而且这样后升级后RPM的问题好像没还有解决啊，有谁能看看啊。
