I'm getting 2.66 instead of thirty-whatever on a 486DX2-80, with a 256KB secondary cache and 32MB of RAM. The annoying thing is, after I come up, I can run the BogoMips *program* and get just peachy, rational output:
Contents of /proc/cpuinfo:
BogoMips : 2.66
BogoMips classic program, run now:
Calibrating delay loop.. ok - 30.78 BogoMips
BogoMips portable program, run now:
Calibrating delay loop.. ok - 39.01 BogoMips
Since the purpose of the delay loop is to get timing, which will then presumably be *used* from time to time, it'd be nice to feel that it was getting the *right* timing. I've posted on this before, would really like to hear something back....
