Linux2.6.24编译可以启动，但是多了一个硬盘，奇怪
我的机器Federa8,自带2.6.23, 我下了一个2.6.24的 配置编译可以启动。但是奇怪的是 我的原理的sata硬盘sda在新内核启动后变成了sdb, 新多了一个8M的硬盘占用了sda, 且这个盘似乎是内存虚拟盘，每次我创建修改后重启动就没有了。 而我用老的内核2.6.23启动，一切正常，我的硬盘仍然是sda. 是内核配置问题吗？附上我的2.6.24的编译配置
[root@localhost ~]# fdisk -l /dev/sda
Disk /dev/sda: 8 MB, 8388608 bytes
8 heads, 32 sectors/track, 64 cylinders
Units = cylinders of 256 * 512 = 131072 bytes
Disk identifier: 0x00000000
Disk /dev/sda doesn't contain a valid partition table

附上启动log, 似乎8M的东西是scsi的一个相关的东西,谁知道吗
