redhat kernel panic 报错信息，求救，谢谢！

birdfly

各位老大，我的一台 华硕 redhat advanced server 2.1 + oracle 8.1.7数据库服务器，
上面只跑了ORACLE数据库服务。但机器出现过多次kernel Panic 的报错，且导致无法telnet ,无法连接。我在/var/log/messages上看到如下日志信息，和屏幕上出现的kernel panic 一样。

请大侠帮我分析一下，这些是什么意思？什么导致数据库服务器kernel panic 啊？谢谢啦~~

我查了资料，这是redhat advanced server 2.1  内核的一个BUG。现在我要进行升级，我想问问，现在升级到哪个版本比较合适？ 我担心新版本又有新BUG
下面两个，用哪个好呢？
kernel-2.4.18-e.41.src.rpm

   40,426,350 kernel-2.4.18-e.43.src.rpm

一般来说，还是越新越好，因为修正了旧版的bug

我选用了  linux-2.4.22,可是我在所有步骤中都显示正常，运行make intall 也都显得正常，可是我就是发现没有生成initrd文件啊。。我运行命令去生成，可总是报错：
[root@aslinux linux-2.4.22]# /sbin/mkinitrd  initrd-2.4.22.img 2.4.22
No module mptbase found for kernel 2.4.22

也查了很多的帖子了，还是不成功。。谁可以帮我一下 ？谢谢啦。。。
