thanks a lot before,i have met some uncertern problem,the cpu's real cache is 4M,but the os could not distinguish it ,now only can i see the cache size is 0KB in /proc/cpuinfo,and then i check the BIOS,and the bios can identify all 4M cache .
i am also trying to recompiler the kernel according to someone's advice one website,i check the right option after doing "make menuconfig " ,i changed the Intel x86-64 to --Generic-x86-64in Processor family (Generic-x86-64) option,and recompil the kernel,and then the problem is as usual.:( pls help me!a tons of thanks.:)
cpu:intel 5160 3.0Ghz
