>Release:        6.0 beta4 for i386
>Organization:
Institute of Software, Chinese Academy of Sciences
>Environment:
vmware 5.0.0 build-13124 on Linux; vmware 5.0.0 build-13124 on windows
>Description:
           I downloaded the 6.0-BETA4 for i386（the md5 checksum is correct）. As with previous versions 5.2& 5.4, I firstly try to install it in vmware. I created the partition and label, and choose the distribution(I tried user and minimal), and commit.  But unfortrunately, after only a short time(when extracting base into / directory), the install failed. I typed the screen output here:
     panic: bio already on queue bp=0xc18e1738
     cpuid = 0

>How-To-Repeat:
