I have an ancient laptop with an AMD-K6 CPU that freezes on boot with 3.2-rc2. The problem was bisected to commit bcb80e53877c2.
The cpuinfo for this box is:
>> cpu.1: cpuinfo ----- /proc/cpuinfo ----- processor : 0 vendor_id : AuthenticAMD cpu family : 5 model : 8 model name : AMD-K6(tm) 3D processor stepping : 12 cpu MHz : 428.804 cache size : 64 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 cx8 pge mmx syscall 3dnow k6_mtrr up bogomips : 857.60 clflush size : 32 cache_alignment : 32 address sizes : 32 bits physical, 32 bits virtual power management:
----- /proc/cpuinfo end -----
This patch is quite simple, thus it appears that rdmsr() is OK, but that rdmsr_safe() is not.
I am happy to provide any other info regarding this box.
Larry
