I confirm that both cores work with newest kernel 2.6.26. I found the following instructions to "ubuntu" the kernel sources (as root): You need the compiler stuff (aptitude install build-essential?) and make-kpkg:
Get linux-2.6.26.tar.bz2, e.g. from www.kernel.org # tar xvfj linux-2.6.26.tar.bz2 # cd linux-2.6.26 # make-kpkg clean # cp /boot/config<your_version> ./oldconfig # make oldconfig Press <return> a lot to confirm default answers ;-) # make-kpkg --initrd --revision cpubug001 kernel_image # cd .. # dpkg -i ./linux-image-2.6.26*deb (This will setup everything in /boot so you can boot the new kernel) After rebooting both cpu cores are listed - yippee-ki-yay! #cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 107 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ stepping : 2 cpu MHz : 1000.000 cache size : 512 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow pni cx16 lahf_lm cmp_legacy svm extapic cr8_legacy 3dnowprefetch bogomips : 2062.69 clflush size : 64 power management: ts fid vid ttp tm stc 100mhzsteps processor : 1 ... core id : 1 ... apicid : 1 initial apicid : 1 ... -- Athlon X2 Dual Core Processor - Second CPU/Core not working with i386 kernel https://bugs.launchpad.net/bugs/213011 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
