求助：安装8.04出现问题

[Zykra]

下载了ubuntu-8.04-desktop-i386.iso 虚拟光驱载入镜像后用wubi安装后第一次重启后出现：

[33.718890]..MP-BIOS bug:8245 timer not connected to IO-APIC
[33.718955]...trying to set up timer(IRQ0) through the 8259A... failed.
[33.719074]...trying to set up timer as Virtual Wire IRQ... failed.
[33.758879]...trying to set up timer as Ext INT IRQ... failed.
[33.898357]kernel panic - not syncing:IO-APIC+timer doesn't work! boot with apic=debug and send a report. Then try booting with the 'noapic' option

随后又下载了ubuntu-8.04.1-desktop-amd64.iso，用同样方法安装，结果安装和使用均正常

机器主要配置：处理器 AMD 64 X2 4400+,主板 ASUS M2N,2G内存，显卡8600GT
经卸载和重装多次后发现只能安装ubuntu-8.04.1-desktop-amd64.iso

在这里想请教大家这是什么问题？
