Do you know of any other issues with memory and or amd64 and the 2.6.16 series? I have run into a weird issue. I have an AMD64 3200+ that runs at 2 GHz and runs *very* cool at about 34c. My motherboard makes it pretty easy to overclock so I have overclocked the 3200+ to 2.2 GHz and it has been running very stable and still only around 39c, though a long compile job did get it to 41c. When I was runing overclocked in 2.6.15 cat /proc/cpuinfo would show: jim@keelie$ cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 47 model name : AMD Athlon(tm) 64 Processor 3200+ stepping : 2 cpu MHz : 2200.000 cache size : 512 KB 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 syscall nx mmxext fxsr_opt lm 3dnowext 3dnow pni lahf_lm ts fid vid ttp tm stc bogomips : 4409.17 Now with 2.6.16 it shows: jim@keelie$ cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 47 model name : AMD Athlon(tm) 64 Processor 3200+ stepping : 2 cpu MHz : 2000.000 ^^^^^^^^^^ <snip> bogomips : 4409.17 The bogomips are showing the same though the kernel is not reporting the correct MHz. Does anyone have a clue what could be causing this? Jim -- gentoo-amd64@g.o mailing list
