Hi Bill ,
Dec 18 01:33:29 belenix unix: [ID 950921 kern.notice] cpu0: x86
(GenuineIntel F33 family 15 model 3 step 3 clock 2400 MHz)
This line (or from "kstat -m cpu_info") says that family = 15 (0xF) and
model = 3 So this criterion
if (!((family == 0xf && model >= 0x3) ||
(family == 0x6 && model >= 0xe))) {
return (B_FALSE);
}
gets satisfied from speedstep.c.
Was the cpudrv drviver present in the kernel version 5.11 ? I used a live CD
so do you feel thats the issue
Thanks & Regards ,
Sathvik
